Asymmetric Synthesis of 4-Substituted 2,6-Dioxopiperidine-3-carbonitrile by Using Thiourea-Catalyzed Asymmetric Michael Addition
摘要:
An enantioselective Michael addition of several alpha,beta-unsaturated carbonyl compounds with malononitrile catalyzed by a bifunctional thiourea is described. We also demonstrate the transformation of Michael adduct into an enantiomerically enriched functionalized piperidine.
