Catalytic enantioselective synthesis of oxindoles and benzofuranones that bear a quaternary stereocenter
Hills, Ivory D.,Fu, Gregory C.

A common feature in indole- and benzofuran-derived natural products is a quaternary stereocenter in the 3-position of the heterocycle. The catalyst (-) -1 promotes the asymmetric synthesis of such compounds 3 (with up to 99% ee) through the rearrangement of O-acylated benzofuranones (X = O) and oxindoles (X = NR2) 2.
