In the presence of a novel chiral catalyst system consisting of tin(II) triflate, a chiral diamine, and tin(II) oxide, highly enantioselective aldol reactions of the silyl enol ether of S-ethyl ethanethioate or S-ethyl propanethioate with aldehydes procee

The asymmetric aldol reaction between both achiral silyl enol ethers of thioesters and aldehydes is efficiently catalyzed by the use of a new catalyst system consisted of tin(II) oxide, trimethylsilyl triflate and a chiral diamine, to give the corresponding adducts in high yields with high diastereo- and enantioselectivities.

A wide variety of aldehydes including aromatic, aliphatic and α,β-unsaturated aldehydes react with silyl enol ether of S-ethyl propanethioate in propionitrile to afford the corresponding aldol-type adducts with high relative and absolute stereochemical co
