The Lewis acid promoted addition of crotyl-n-tributylstannane to a nor-ephedrine-derived 2-methoxy-oxazolidine has been studied.This stereoconvergent reaction allows highly selective C-C bond formation and takes place with opposite stereochemistry with respect to the analogous silylketenethioacetal addition.This result suggests a preference for a synclinal transition state geometry.
