Catalytic asymmetric allylic transfer reaction: (4-trimethylsilylbut-2-ynyl)stannane as a new reagent leading to the enantioselective synthesis of dienyl alcohols

Abstract

Catalytic enantioselective addition of (4-trimethylsilylbut-2-ynyl)tributylstannane to aldehydes provides trimethylsilylmethylallenyl alcohols in high enantioselectivity which can be converted with a second electrophile to the corresponding dienyl alcohols.
