An Efficient Chiral Promoter in the Aldol-type Reaction. Chiral Diamine Coordinated Tin(II) Triflate–Dibutyltindiacetate Complex

Abstract
An efficient chiral promoter, chiral diamine coordinated tin(II) triflate–dibutyltindiacetate complex, promotes the asymmetric aldol type reaction between both achiral silyl enol ethers derived from thioesters and a wide variety of aldehydes in high yields with perfect stereochemical control.
