Aldol reaction of aldehydes with difluomketene ethyl trimethylsilyl acetal (1) in the presence of a substoichiometric amount of chiral Lewis acid 2 or 3 provides the corresponding ~,a-difluom hydroxy esters 4-12 with high enantioselectivitles (up to 98% ee). Reaction temperature has a great influenc
