The Mukaiyama-Michael reaction of 2-(trimethylsilyloxy)furan with α′-phenylsulfonyl enones using bis(oxazoline)-copper(II) complexes as chiral catalyst provides the γ-butenolides in high enantio- and diastereoselectivity. This approach is very useful for the enantioselective synthesis of γ-butenolide derivatives under chiral Lewis acid catalysis.
