When treated with an alkoxide base like t-BuOK in aprotic solvent, N-diphenylmethyl imino oxindoles, made conveniently through condensation of corresponding isatins with N-diphenylmethyl amine, are deprotonated to form azaallyl anions. Allylation and alkylation of this type of intermediates proceed smoothly with diverse C-electrophiles. Acidic work up finishes 3-amino-3-allyl/alkyl oxindoles. The overall transformation equals to an umpolung process at the C3 of isatins. (c) 2021 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

A highly enantioselective iridium- or ruthenium-catalyzed intermolecular reductive amination/asymmetric hydrogenation relay with 2-quinoline aldehydes and aromatic amines has been developed. A broad range of sterically tunable chiral N,N’-diaryl vicinal diamines were obtained in high yields (up to 95%) with excellent enantioselectivity (up to >99% ee). The resulting chiral diamines could be readily transformed into sterically hindered chiral N-heterocyclic carbene (NHC) precursors, which are otherwise difficult to access. The usefulness of this synthetic approach was further demonstrated by the successful application of one of the chiral vicinal diamines and chiral NHC ligands in a transition-metal-catalyzed asymmetric Suzuki-Miyaura cross-coupling reaction and asymmetric ring-opening cross-metathesis, respectively.

Overexpression of ABC transporters like P-glycoprotein (P-gp) has been correlated with resistances in cancer chemotherapy. Intensive efforts to identify P-gp inhibitors for use in combination therapy have not led to clinically approved inhibitors to date. Here, we describe computational approaches combined with structure-based design to improve the characteristics of a P-gp inhibitor previously identified by us. This hit compound represents a novel class of P-gp inhibitors that specifically targets and inhibits P-gp ATP hydrolysis while not being transported by the pump. We describe here a new program for virtual chemical synthesis and computational assessment, ChemGen, to produce hit compound variants with improved binding characteristics. The chemical syntheses of several variants, efficacy in reversing multidrug resistance in cell culture, and biochemical assessment of the inhibition mechanism are described. The usefulness of the computational predictions of binding characteristics of the inhibitor variants is discussed and compared to more traditional structure-based approaches.

A visible light-induced and exogenous photo-sensitizer-free, copper-catalyzed radical aminocarbonylation of cycloketone oxime esters with CO gas and amines is developed. The mild catalytic system involving CuCl and N,N,N-tridentate ligand shows good reactivity and chemo-selectivity, and tolerates a wide range of cycloketone oxime esters and alkyl/aryl amines, giving the corresponding cyanoalkylated amides in moderate to good yields. Preliminary mechanistic studies suggest that the reaction involves a Cu-I/(CuCuIII)-Cu-II/-based catalytic cycle and radical intermediate.

The development of efficient and eco-friendly methods for the synthesis of elaborate amines is highly desired as they are valuable chemicals. The catalytic alkylation of amines using alcohols as alkylating agents, through the so-called borrowing hydrogen process, satisfies several of the principles of green chemistry. In this paper, four neutral half-sandwich complexes of Ru(II), Rh(III), and Ir(III) have been synthesized and tested as catalysts in theN-benzylation of amines with benzyl alcohol. The new derivatives contain aN(boolean AND)N ‘ anionic ligand derived from 5-(pyridin-2-ylmethylene)hydantoin (Hpyhy) that has never been tested in metal complexes with catalytic applications. In particular, the Ir derivatives, [(Cp*)IrX(pyhy)] (X = Cl or H), exhibit high activity along with good selectivity in the process. Indeed, the scope of the optimized protocol has been proved in the benzylation of several primary and secondary amines. The selectivity towards monoalkylated or dialkylated amines has been tuned by adjusting the amine:alcohol ratio and the reaction time. Experimental results support a mechanism consisting of three consecutive steps, two of which are Ir catalyzed, and a favorable condensation step without the assistance of the catalyst. Moreover, an unproductive competitive pathway can operate when the reaction is performed in open-air vessels, due to the irreversible release of H-2. This route is hampered when the reaction is carried out in close vessels, likely because the release of H(2)is reversed through metal-based heterolytic cleavage. From our viewpoint, these results show the potential of the new catalysts in a very attractive and promising methodology for the synthesis of amines.

Several phenoxy-imine ligands bearing o-trityl group in phenoxy moiety RN=CHArOH (Ar = C6H2(CPh3)Bu-t, R = 2,6-Me2C6H3 (L1H); 2,6-(Pr2C6H3)-Pr-i (L2H); 3,5-(CF3)(2)C6H3 (L3H); 3,5-(OMe)(2)C6H3 (L4H); CHPh2 (L5H); CPh3 (L6H)) were synthesized and characterized by H-1 NMR and C-13 NMR spectroscopy. The vanadium complexes based on these ligands LVCl2(THF)(2) (1-6) were synthesized via conventional transmetalation reaction in moderate to high yields. Complexes 1-6 were fully characterized by FT-IR, elemental analyses and the molecular structures of 1, 2 center dot H2O, (2 center dot H2O)(2)(mu-Cl)(2), 4, and 5 were confirmed by X-ray crystallographic analysis in which the six-coordinated vanadium centers are in a typical octahedral geometry. Upon activation with Et2AlCl in toluene, complexes 1-6 showed high activities in ethylene polymerization affording polymers with moderate molecular weight (5.9-11.8 x 10(4) Da). Moreover, in hexane or CH2Cl2, 1-6/Et2AlCl exhibited enhanced activities. When activated with MAO or MMAO in toluene, these complexes showed relatively low activities but afforded polymers with ultra-high molecular weight (up to 3.30 x 10(6) Da). 1-6/Et2AlCl also showed high activities in ethylene/1-hexene copolymerization at room temperature giving moderate molecular-weight polymers (6.5-11.4 x 10(4) Da) with co-monomer incorporation being of 6.0 similar to 7.8%.

The aldol reaction which is the most important one among the C-C bond forming reactions, is widely used by synthetic organic chemists to obtain beta-hydroxycarbonyl compounds which are important starting components for biologically active compounds in optically pure form. In this research, five Pro-Phe derivatives were synthesized by simple amidation reactions and characterized by their spectral data. Their catalytic activities in asymmetric aldol reaction were investigated. The catalytic activity studies were performed with aliphatic ketones and various aromatic aldehydes. Especially, (S)methyl 3-mercapto-2-(S)-3-phenyl-2-((S)-pyrrolidine-2-carboxamido)propanamido)propanoate showed good catalytic activities in water at 0 degrees C in the presence of p-nitrobenzoic acid cocatalyst. The enantioselectivities were up to 90.4%, the diastereomeric ratios were up to 97/3 and yields were 99%. The results showed that these organocatalysts were promising organocatalysts for aldol reaction. Besides, this catalyst showed its best catalytic activities in water which is also an important contribution to green chemistry requirements.

A series of phosphonic acid and bisphosphoramidate derivatives were synthesized and characterized. The bioactivities against the fungal pathogen Macrophomina phaseolina and human acetylcholinesterase AChE enzyme were studied using QSAR based on multiple linear regression. L17, with (p-Cl-C6H4-NH) (p-Cl-C6H4)C(H)P(O)(OC2H5)(2) skeleton, demonstrated a great mortality on the M. phaseolina mycelial growth by 83% inhibition at 150 mg/L; the other tested derivative showed moderate to weak antifungal activity against the fungus. QSAR model based on the GA-MLR method revealed the importance of 3D descriptors (De, Mor18e, H8m, and Mor30p) on the antifungal activity. It showed good capability in predicting the fungicidal activity of the studied molecules. Another derivative, L5, with (m-CH3-NC5H4-NH)(m-CH3-C6H4)C(H)P(O)(OCH3)(2) skeleton displays the most potent anti-AChE activity. The electronic parameters, Delta EL-H, and E-LUMO, have the highest contribution of human AChE. The authors suggest that these models could be usefully employed in designing more effective crop protection compounds without side effects on non-target organisms.

A method for generation of Pd/phosphite-oxazoline catalysts containing an alkyl backbone chain has been successfully applied to Pd-catalyzed allylic substitution reactions. By carefully selecting the substituents at both the alkyl backbone chain and the oxazoline of the ligand, as well as the configuration of the biaryl phosphite group, high activities (TOF > 8000 mol substrate X (mol Pd X h)(-1)) and excellent enantioselectivities (ee’s up to 99%) have been achieved for many hindered and unhindered substrates with a wide range of C-, O-, and N-nucleophiles (73 substitution products in total). Moreover, DFT and NMR studies of the key Pd-allyl complexes allowed us to better understand the origin of the excellent enantioselectivities observed experimentally. The useful application of the Pd/phosphite-oxazoline catalysts was demonstrated by the syntheses of many chiral carbobicycles, with multiples stereocenters, by simple sequential reactions involving Pd-allylic substitution and either 1,6-enyne cyclization or Pauson-Khand enyne cyclization.
