A highly regioselective reaction of allylic acetates with silylated carbon nucleophiles directed by a sulfenyl group
摘要:
(alpha-Sulfenylmethyl)allyl acetates reacted with silylated carbon nucleophiles in the presence of a catalytic amount of a Lewis acid to give mainly alpha-adducts at the sulfenylmethyl group in moderate to good yields with high regioselectivity. The reaction may proceed via episulfonium ion intermediates.
