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