1,5-Asymmetric induction in reactions of δ-alkoxyallylstannanes: stereoselective reactions with chiral aldehydes
摘要:
Transmetallation of (4S,2E)-4-phenylmethoxypent-2-enyl(tributyl)stannane 1 using tin(IV)chloride generates a reagent which shows excellent 1,5-stereoselectivity in reactions with aldehydes: with chiral aldehydes, the stereochemical preference of the reagent dominates the course of the reaction.
