ChemInform Abstract: Organocatalytic Asymmetric Vinylogous Michael Addition of 3-(2-Oxoindolin-3-ylidene)butanoates to Nitroalkenes Catalyzed by a Bifunctional Cinchona-Based Squaramide.
摘要：
An efficient, enantioselective, vinylogous Michael addition of 3-(2-oxoindolin-3-ylidene)butanoates to nitroalkenes is presented which is catalyzed by a cinchona alkaloid-derived squaramide.
