Influence of the Reaction Conditions on the Evolution of the Michael Addition of β‐Keto Sulfones to α,β‐Unsaturated Aldehydes

Abstract

AbstractWe have studied the influence of different reaction conditions on the conjugated addition of β‐keto sulfones to α,β‐unsaturated aldehydes catalyzed by silyl prolinol ethers. Small changes in the starting material and/or in the experimental protocol are able to produce significant variations in the structures of the final products. The high chemical versatility of the resulting Michael adducts make possible their use in a variety of tandem and one‐pot reactions to afford polysubstituted cyclic products bearing multiple chiral centers.
