studied the influence of different reactionconditions 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
