摘要
α,β-不饱和羰基化合物的选择性还原具有很重要的应用意义,同时具有很大挑战性,利用有机小分子催化剂、以二氢吡啶酯为氢源可以高化学选择性、高对映选择性地催化还原α,β-不饱和羰基化合物的共轭双键。综述了有机小分子催化剂在α,β-不饱和醛、酮、酯以及串联反应中共轭碳碳双键选择性催化还原的研究进展,总结了每一催化体系的优缺点。
The selective reduction of α,β-unsaturated carbonyl compounds is a process with significantly valuable but challenging significance.Organocatalysts can reduce the conjugate C=C bonds with high chemoselectivity and enantioselectivity using the Hantzsch esters(dihydropyridine esters) as the hydrogen source.This review focused on recent developments in selectively organocatalytic reduction of conjugate C=C bonds in the α,β-unsaturated aldehydes,α,β-unsaturated ketones,α,β-unsaturated esters and cascade reactions.The potential strengths of each catalytic system as well as its weaknesses were discussed.
