Asymmetric conjugate additions of branched aldehydes to vinyl sulfones promoted by sulfonamide organocatalyst 6 or 7 have been developed, allowing facile synthesis of the corresponding adducts with all-carbon quaternary stereocenters in excellent yields with up to 95% ee.
已开发出由磺酰胺有机催化剂 6 或 7 促进的支化醛与乙烯基砜的不对称共轭加成,可以轻松合成具有全碳四元立体中心的相应加合物,收率高达 95% ee。
