Abstract
Trifluoromethyl aldimines reacted with trimethylsilyloxyfuran in presence of Lewis acids to provide butenolides in high yields with total diastereoselectivity (>98%). The configuration of these products is anti. The butyrolactone 4a, substituted with a 2-trifluoromethyl ethyl amine, could be converted into a trans α-trifluoromethyl piperidine derivative.
