Highly Efficient Asymmetric Conjugate Additions of Aldehydes with Vinyl Sulfones Using a Sulfonamide Organocatalyst
[摘要]:A sulfonamide organocatalyst promotes the asymmetric conjugate addition of branched aldehydes to vinyl sulfones to afford the corresponding adducts with all-carbon quaternary stereocenters in excellent yields with up to 95% ee.
