A stereoselective amination/cyclization cascade process has been developed that allows for the preparation of a series of unsaturated and substituted caprolactam derivatives in good yields. This conceptually novel protocol takes advantage of the easy access and modular character of vinyl gamma-lactones that can be prepared from simple precursors. Activation of the lactone substrate in the presence of a suitable Pd precursor and newly developed phosphoramidite ligand offers a stereocontrolled ring-opening/allylic amination manifold under ambient conditions. The intermediate (E)-configured epsilon-amino acid can be cyclized using a suitable dehydrating agent in an efficient one-pot, two-step sequence. This overall highly chemo-, stereo- and regio-selective transformation streamlines the production of a wide variety of modifiable and valuable caprolactam building blocks in an operationally attractive way.

Herein, we broaden the application scope of (cyclopentadienone)iron complexes 1 in C=N bond reduction. The catalytic scope of pre-catalyst 1b, which is more active than the Knolker complex (1a) and other members of its family, has been expanded to the catalytic transfer hydrogenation (CTH) of a wider range of aldimines and ketimines, either pre-isolated or generated in situ. The kinetics of 1b-promoted CTH of ketimine S1 were assessed, showing a pseudo-first order profile, with TOF = 6.07 h(-1) at 50 % conversion. Moreover, the chiral complex 1c and its analog 1d were employed in the enantioselective reduction of ketimines and reductive amination of ketones, giving fair to good yields and moderate enantioselectivity.

We report the synthesis of alpha-aminonitriles by one-pot coupling reaction of aldehyde, amines and trimethylsilyl cyanide (TMSCN) using beta-ketoiminato zinc complexes as a pre-catalyst in very good yield under mild reaction condition. Homoleptic zinc complex [{kappa(2)-(2,4,6-Me3C6H2NC(Me)=CHC(Me)=O)}(2)Zn] (1 a) was synthesized by the treatment of protic ligand [(2,4,6-Me3C6H2NHC(Me)=CHC(Me)=O)] ((LH)-H-1) with potassium hydride and anhydrous zinc diiodide in 2 : 2 : 1 molar ratio in THF. Analogous reactions using [(2,6-(Pr2C6H3NHC)-Pr-i(Me)=CHC(Me)=O)] ((LH)-H-2) and [(Ph2CHNHC(Me)=CHC(Me)=O)] ((LH)-H-3) as protic ligands, dinuclear zinc complexes [{kappa(3)-(2,6-(Pr2C6H3NC)-Pr-i(Me)=CHC(Me)=O)}ZnI](2)(1 b) and [Zn(Ph2CHNHC-(Me)=CHC(Me)=O)ZnI2] (1 c) were obtained in good yield. Molecular structures of ligandsL(1)H,(LH)-H-3, and zinc complexes1 a,1 b, and1 cwere established by single-crystal x-ray diffraction analysis. Dinuclear zinc complexes1 b, and1 cexhibited high transformation, greater selectivity and broad substrate scope for the synthesis of alpha-aminonitrile under mild condition. A most plausible mechanism for synthesis alpha-aminonitrile is proposed based on several controlled reactions.

Supported by their involvement in many neurodegenerative disorders, muscarinic acetylcholine receptors ( mAChRs) are an interesting target for PET imaging. Nevertheless, no radiotracer is established in clinical routine. Within this work we aim to develop novel PET tracers based on the structure of arecoline. Fifteen novel arecoline derivatives were synthesized, characterized and tested for their affinity to the mAChRs M1-M5 and the conceivable off-target acetylcholinesterase. Five arecoline derivatives and arecoline were labeled with carbon-11 in good yields. Arecaidine diphenylmethyl ester (3b), arecaidine bis(4-fluorophenyl)methyl ester (3c) and arecaidine (4-bromophenyl)(4-fluorophenyl)methyl ester (3e) showed a tremendous gain in mAChR affinity compared to arecoline and a pronounced subtype selectivity for M1. Metabolic stability and serum protein binding of [C-11] 3b and [C-11] 3c were in line with properties of established brain tracers. Nonspecific binding of [C-11]3c was prevalent in kinetic and endpoint experiment on living cells as well as in autoradiography on native mouse brain sections, which motivates us to decrease the lipophilicity of this substance class prior to in vivo experiments.

Enantioselective reduction of ketimines was demonstrated using chiral N-heterocyclic carbene (NHC)-stabilised borenium ions in frustrated Lewis pair catalysis. High levels of enantioselectivity were achieved for substrates featuring secondary N-alkyl substituents. Comparative reactivity and mechanistic studies identify key determinants required to achieve useful enantioselectivity and represent a step forward in the further development of enantioselective FLP methodologies.

Proton transfer processes mediate many organic reactions. How to realize stereochemical control of this process has always been a challenging topic in the field of asymmetric catalysis. In this study, N-(diphenylmethyl)-1-phenylethan-1-imine (Schiff base derived from 2,2-diphenylethan-1-amine and acetophenone) was used as substrate, and different near neutral solvents and various chiral metal complex catalysts were used to carry out photoinduced C=N double bond transfer in the substrate under irradiation with a mercury ultraviolet lamp. The double bond transfer in the substrate molecule was highly selective. Solvents containing strong electronegative atoms like oxygen and chlorine, such as alcohols, aldehydes, and carbon tetrachloride, were more effective than other solvents under high light intensity. The 1,3-proton transfer process involves photoexcitation of the Schiff base and coordination of the latter to the central metal atom of the chiral catalyst, so that the substrate molecule is placed in a stable chiral environment to form a transition state. The strongly electronegative atom of the near-neutral solvent attracts the active a-hydrogen from the excited Schiff base molecule to form a negatively charged delocalized p-bond structure. The subsequent proton addition yields more stable molecular structure to complete the selective proton transfer process. Among the examined chiral catalysts, divalent tin porphyrin was the most effective, and the product yield and enantiomeric excess were 98% and 91.49%, respectively. The described photoinduced C=N double bond transfer in N-(diphenylmethyl)-1-phenylethan-1-imine is characterized by mild conditions (room temperature), high stereoselectivity, and simple operation.

Ubiquitin-like protein neddylation is overactivated in various human cancers and correlates with disease progression, and targeting this pathway represents a valuable therapeutic strategy. Our previous work disclosed an antihypertensive agent, candesartan cilexetic (CDC), serves as a novel neddylation inhibitor for suppressing tumor growth by targeting Nedd8-activating enzyme (NAE). In this study, 42 benzimidazole derivatives were designed and synthesized based on lead compound CDC to improve the neddylation inhibition and anticancer efficacy. Optimal benzimidazole-derived 35 displayed superior neddylation inhibition in enzyme assay compared to CDC (IC50 = 5.51 mu M vs 16.43 mu M), along with promising target inhibitory activity and killing selectivity in cancer cell. The results of cellular mechanism research combined with tumor growth suppression in human lung cancer cell A549 in vivo, accompanied with docking model, revealed that 35 has the potential to be developed as a promising neddylation inhibitor for anticancer therapy.
