addition–protonation reactions of alkylidene Meldrum’s acids to α-substituted vinyl ketones have been developed by using a chiral primary amine as the organocatalyst, affording the products in excellent yields and with good enantioselectivity. One-pot three-component tandem reduction–Michael addition–protonation reactions of alkylidene Meldrum’s acids to α-substituted vinyl ketones have been developed
摘要 通过使用手性伯胺作为有机催化剂,开发了亚烷基梅尔德鲁姆酸与α-取代的乙烯基酮的一锅三组分串联还原-迈克尔加成-质子化反应,从而提供了具有优异收率和良好对映选择性的产物。 通过使用手性伯胺作为有机催化剂,开发了亚烷基梅尔德鲁姆酸与α-取代的乙烯基酮的一锅三组分串联还原-迈克尔加成-质子化反应,从而提供了具有优异收率和良好对映选择性的产物。
