5-Ene-4-thiazolidinones – An efficient tool in medicinal chemistry

The presented review is an attempt to summarize a huge volume of data on 5-ene-4-thiazolidinones being a widely studied class of small molecules used in modern organic and medicinal chemistry. The manuscript covers approaches to the synthesis of 5-ene-4-thiazolidinone derivatives: modification of the C5 position of the basic core; synthesis of the target compounds in the one-pot or multistage reactions or transformation of other related heterocycles. The most prominent pharmacological profiles of 5-ene derivatives of different 4-thiazolidinone subtypes belonging to hit-, lead-compounds, drug-candidates and drugs as well as the most studied targets have been discussed. Currently target compounds (especially 5-en-rhodanines) are assigned as frequent hitters or pan-assay interference compounds (PAINS) within high-throughput screening campaigns. Nevertheless, the crucial impact of the presence/nature of C5 substituent (namely 5-ene) on the pharmacological effects of 5-ene-4-thiazolidinones was confirmed by the numerous listed findings from the original articles. The main directions for active 5-ene-4-thiazolidinones optimization have been shown: i) complication of the fragment in the C5 position; ii) introduction of the substituents in the N3 position (especially fragments with carboxylic group or its derivatives); iii) annealing in complex heterocyclic systems; iv) combination with other pharmacologically attractive fragments within hybrid pharmacophore approach. Moreover, the utilization of 5-ene-4-thiazolidinones in the synthesis of complex compounds with potent pharmacological application is described. The chemical transformations cover mainly the reactions which involve the exocyclic double bond in C5 position of the main core and correspond to the abovementioned direction of the 5-ene-4-thiazolidinone modification.

The endocannabinoid system – current implications for drug development

In this review, the state of the art for compounds affecting the endocannabinoid (eCB) system is described with a focus on the treatment of pain. Amongst directly acting CB receptor ligands, clinical experience with increment Delta(9)-tetrahydracannabinol and medical cannabis in chronic non-cancer pain indicates that there are differences between the benefits perceived by patients and the at best modest effect seen in meta-analyses of randomized controlled trials. The reason for this difference is not known but may involve differences in the type of patients that are recruited, the study conditions that are chosen and the degree to which biases such as reporting bias are operative. Other directly acting CB receptor ligands such as biased agonists and allosteric receptor modulators have not yet reached the clinic. Amongst indirectly acting compounds targeting the enzymes responsible for the synthesis and catabolism of the eCBs anandamide and 2-arachidonoylglycerol, fatty acid amide hydrolase (FAAH) inhibitors have been investigated clinically but were per se not useful for the treatment of pain, although they may be useful for the treatment of post-traumatic stress disorder and cannabis use disorder. Dual-acting compounds targeting this enzyme and other targets such as cyclooxygenase-2 or transient potential vanilloid receptor 1 may be a way forward for the treatment of pain.

Asymmetric epoxidation of alpha,beta-unsaturated ketones catalyzed by rare-earth metal amides RE[N(SiMe3)(2)](3) with chiral TADDOL ligands

The catalytic asymmetric epoxidation of alpha,beta-unsaturated ketones by tert-butylhydroperoxide (TBHP) has been well established using rare-earth metal amides RE[N(SiMe3)(2)](3) (RE = La(1), Nd(2), Sm(3), Y(4), Yb(5)) with chiral TADDOL ligands. It was found that the combination of Yb[N(SiMe3)(2)](3) and chiral TADDOL ligand H2L2 ((4S,5S)-2,2-dimethyl-alpha,alpha,alpha ‘,alpha ‘-tetra-3,5-bis(trifluormethylphenyl)-1,3-dioxolane-4,5-dimethanol) in a 1 : 1 molar ratio was the optimal choice, which provided the desired epoxides in excellent yields (89-99%) and good to high enantioselectivities (57-94% ee), using DBU as an additive. Various substrates were proved to have functional group tolerance. In addition, gram-level experiments and derivatization experiments were also studied.

Hydride Amide and Hydride Phenolate Complexes of NHC Coordinated Aluminum

The reaction of NHC alane adducts NHC center dot AlH3 (NHC = N-Heterocyclic Carbene; NHC = iPr(2)Im, Dipp(2)Im; R(2)Im = 1,3-di-organyl-imidazolin-2-ylidene; iPr = isopropyl; Dipp = 2,6-diisopropylphenyl) with secondary amines HNR2 [R = iPr, Ph, Si(CH3)(3)] and the reaction of the trimethylamine alane adduct (NMe3)center dot AlH3 with secondary amines followed by the reaction with the NHC both lead to formation of the compounds NHC center dot AlH2(NR2) 1-6 [NHC = iPr(2)Im, Dipp(2)Im, R = iPr, Ph, Si(CH3)(3)]. These compounds are stable in solution up to temperatures of 90 degrees C. In contrast to the NHC alane adduct (iPr(2)Im)center dot AlH3 (I) and (Dipp(2)Im)center dot AlH3 (II), no ring expansion reaction to six-membered heterocyclic rings or ring opening reaction were observed for the reaction of (iPr(2)Im)center dot AlH2(NR2) with another equivalent of the NHCs iPr(2)Im or Dipp(2)Im. Thus, amide substituted NHC alane adducts show a much high stability compared to the parent compounds NHC center dot AlH3. Furthermore, the reaction of NHC center dot AlH3 (NHC = iPr(2)Im, Dipp(2)Im) with 2,4,6-trimethylphenol leads to the formation of the adducts NHC center dot AlH3-n(OMes)(n) 7-10 (n = 1, 2). The reaction with n >= 3 equivalent of 2,4,6-trimethylphenol afforded the imidazolium salt [Dipp(2)ImH](+)[Al(OMes)(4)](-) (11). The compounds 7-11 are also stable with respect to ring expansion after addition of another equivalent NHC.

Stereoselective Sulfinyl Aniline-Promoted Pd-Catalyzed C-H Arylation and Acetoxylation of Aliphatic Amides

Stereoselective functionalization of aliphatic C-H bonds presents a great challenge. Following this target, we disclose herein an original strategy towards direct arylation of aliphatic chains at ss-methylene position based on a use of amide-sulfoxide bicoordinating directing group. Although moderate to high chiral induction (up to 9:1d.r.) is achieved, diastereomerically pure compounds may be afforded by simple separation of diastereomeric products by silica gel chromatography. Accordingly, this reaction allows preparation of a large scope of high-value scaffolds in synthetically useful yields while recyclable character of our chiral auxiliary brings an additional benefit. A potential of this methodology to build up original molecules by sequential diarylation and expedient (two step) synthesis of a biologically active compound are further disclosed. Finally a first example of stereoselective direct acetoxylation of aliphatic chains is reported.

The endocannabinoid system: Novel targets for treating cancer induced bone pain

Treating Cancer-induced bone pain (CIBP) continues to be a major clinical challenge and underlying mechanisms of CIBP remain unclear. Recently, emerging body of evidence suggested the endocannabinoid system (ECS) may play essential roles in CIBP. Here, we summarized the current understanding of the antinociceptive mechanisms of endocannabinoids in CIBP and discussed the beneficial effects of endocannabinoid for CIBP treatment. Targeting nonselective cannabinoid 1 receptors or selective cannabinoid 2 receptors, and modulation of peripheral AEA and 2-AG, as well as the inhibition the function of fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) have produced analgesic effects in animal models of CIBP. Management of ECS therefore appears to be a promising way for the treatment of CIBP in terms of efficacy and safety. Further clinical studies are encouraged to confirm the possible translation to humans of the very promising results already obtained in the preclinical studies.

Synthesis, structure and catalytic activity of rare-earth metal amino complexes incorporating imino-functionalized indolyl ligand

The reactions of the imino-functionalized indolyl ligand (HL, L = 3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5N) with the rare-earth metal amides [(Me3Si)(2)N](3)RE(mu-Cl)Li(THF)(3) producing different types of rare-earth metal amido complexes were investigated. The reactions of HL with 1 equiv. of [(Me3Si)(2)N](3)RE(mu-Cl)Li(THF)(3) generated a series of hetero-nuclear bimetallic rare-earth metal amino complexes {[eta(1):mu-eta(2)-3-(4-Me2N-C6H4CH=N-CH2CH2)C-8 H-5]RE[N(SiMe3)(2)](2)(mu-Cl)Li(THF)} (RE = Y(1 ), Sm(2), Gd(3), Er(4), Yb(5)). By extending the reaction time, only the reaction of HL with [(Me3Si)(2)N](3)Gd(mu-Cl)Li(THF)(3) gave an unexpected binuclear rare-earth metal complex {[(mu-eta(5) :eta(1)):eta(1):eta(1)-3-[(Me2N)(2)-C14H9]-(NCH2CH2-C8H5N)(2)]Gd-2[N(SiMe3)(2)](3)} (6 ) incorporating a novel polycyclic ligand through C-C and C-N coupling. Treatment of HL with [(Me3Si)(2)N](3)Sm(mu-Cl)Li(THF)(3) in a 2:1 ratio generated the bis(indolyl) heteronuclear bimetallic rare-earth metal amino complex {(eta(1):eta(1)-[mu eta(2):eta(1)-3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5]Li[mu-eta(2):eta(1)-3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5])Sm[N(SiMe3)(2)](2)} (7) in low yield probably due to accompanying with the formation of the complex 2 . The above results indicated that reaction conditions play important roles in the formation of different coordination modes of the imino-functionalized indolyl rareearth metal amido complexes. All new complexes 1-7 are fully characterized including X-ray structural determination. The catalytic activity of complexes 1 7 for the addition of amines to carbodiimides was explored. The results showed that all complexes displayed an excellent activity towards the addition of amines to carbodiimides producing guanidine under solvent-free condition. (C) 2020 Elsevier B.V.

Microconine [N-methyl-2-methyl-3-methoxy-6-(deca-l’,3 ‘,5 ‘-trienyl) piperidine, an alkaloid from Microcos paniculata]: Synthesis, stereochemistry and spectroscopic data

Unambiguously corrected H-1 NMR data for the originally isolated sample of microconine [N-methyl-2-methyl-3-methoxy-6-(deca-l’,3′,5′-trienyl)piperidine], an alkaloid found in Microcos paniculata, are reported. The asymmetric synthesis of the (2S,3R,6S)- and (2S,3S,6S)-stereoisomeric forms [epimeric at C(3)] of this compound allows the unambiguous assignment of the relative 2,3-cis-3,6-cis-configuration of the natural product. The synthesis uses the conjugate addition of enantiopure lithium (S)-N-benzyl-N-(alpha-methylbenzyl)amide to tert-butyl crotonate and ensuing enolate oxidation with (+)-camphorsulfo-nyloxaziridine to generate the requisite C(2) and C(3) stereogenic centres found within the target. After elaboration, an intramolecular reductive amination was used to form the piperidine ring, with concomitant formation of the C(6) stereogenic centre. Comparison of specific rotation data is consistent with the alkaloid having the absolute (2R,3R,6R)-configuration. (C) 2020 Published by Elsevier Ltd.
