Abstract

A low loading of a proazaphosphatrane compound efficiently catalyzes the reaction of trimethylsilylacetonitrile (TMSAN) with aldehydes for the synthesis of β-hydroxynitriles under mild reaction conditions. Various functional groups were tolerated, and good to excellent yields were obtained.
