Catalytic Asymmetric Reductive Addition of Olefins to Aldehydes Mediated by Boron and Zinc Organometallics

Schwink, Lothar,Knochel, Paul

, p. 9007 - 9010 (2007/10/02)

A procedure involving a hydroboration, boron-zinc exchange and asymmetric addition to an aldehyde allows the reductive addition of olefins to aldehydes in 50-96percent ee.A short and efficient 3 step synthesis of ginnol (61percent overall yield, 92percent ee) demonstrates the synthetic utility of the method.
