Synthesis and biological evaluation of novel 3,4-diaryl lactam derivatives as triple reuptake inhibitors
摘要:
A series of 3,4-diarylpyrrolidin-2-one was designed, prepared and evaluated as triple reuptake inhibitors for antidepressant. Most compounds exhibited comparable in vitro efficacy as norepinephrine and dopamine transporter reuptake inhibitors. Especially, 2i showed better potency than GBR-12909 (IC50 = 14 - nM) which was used as reference compound for dopamine transporter. In addition, 2a and 2b showed inhibition (5.17 mu M-85.6 nM) for three transporters. (C) 2013 Elsevier Ltd. All rights reserved.
of α,β-unsaturated methyl ketone/nitro compounds from benzylic amines through an oxidation–aldol/Henry reaction is reported. The reaction proceeded well by using MCPBA as oxidant and CuCl2·2H2O as catalyst. A variety of functionalized α,β-unsaturated methyl ketone/nitro compounds were assembled in moderate yields by application of this catalytic one-pot reaction.

A thiourea-catalyzed biomimetic reduction of conjugatednitroalkenes has been developed. Various aromatic and aliphatic conjugatednitroalkenes can be reduced to give the respective nitroalkanes with good yields under mild conditions. This protocol is not only practical, but may also provide insight into the mechanisms of redox transformations in biological systems.

triamine 4 has been developed as a highly efficient and stereoselective organocatalyst for the asymmetric Michaeladdition of cyclohexanone to nitroolefins. In the presence of (CF3SO2)2NH, 4 catalyzed the reaction of cyclohexanone to a variety of nitroolefins with high yields (up to 99%) and excellent diastereoselectivities (up to 99:1 dr) and enantioselectivities (up to 98% ee).

Multifunctional isoquinoline-oxazolines (MIQOXs) were conceived and synthesized from commercially available chiral amino acids. The multifunctional role of MIQOXs was demonstrated by Pd-catalyzed highly enantioselective addition of arylboronic acids to nitrostyrenes, and by the discovery of novel antifungal candidates.
