A Highly Practical and Enantioselective Reagent for the Allylation of Aldehydes

Abstract

Strain at silicon is the key to success of reagent 1 since this strain, which is induced by the diazasilacyclopentane ring, determines its reactivity. This practical and general new reagent for the highly enantioselective allylation of aldehydes is easily prepared as an air-stable solid and may be stored without significant decomposition.
