Alpha-Amidoalkylation of allyltrimethylsilane with (-)- and nthyl-2-(o
-Chlorobenzoylamino)-2-halogenoethanoate (2, 4a and 4b) gave in the pr
esence of zinc chloride. separable mixtures of the diastereomers (-)-
and (+)-menthyl-2-(o-Chlorobenzoylamino)-4-pentenoate (5a, 5b and 6a,
6b). The absolute configurations of 5a, 5b and 6a, 6b were determined
through conversion of 5a into S-(+)-norvaline hydrochloride.
