A novel organocatalytic approach for aza-Michael reaction of chalcones using commercial and non-expensive O-benzyl-hydroxylamine and a readily available organocatalyst is provided. The use of this simple protocol results in beta-keto hydroxylamines in up to 60% ee, thus extending the generality of the catalytic enantioselective aza-Michael reaction.

Abstract

A novel organocatalytic approach for aza-Michael reaction of chalcones using commercial and non-expensive O-benzyl-hydroxylamine and a readily available organocatalyst is provided. The use of this simple protocol results in beta-keto hydroxylamines in up to 60% ee, thus extending the generality of the catalytic enantioselective aza-Michael reaction.
