The catalytic asymmetric Mannich-type reactions in aqueous media.

Shū Kobayashi1, Tomoaki Hamada, Kei Manabe.   

Abstract

The catalytic, diastereo- and enantioselective Mannich-type reaction of a hydrazono ester with silyl enol ethers in aqueous media has been successfully achieved with ZnF(2), a chiral diamine ligand, and trifluoromethanesulfonic acid.
