title: Rapid entry to enantiopure carbacepham derivatives via Lewis acid promoted carbonyl-ene cyclization of 2-azetidinone-tethered alkenylaldehydes.
abstract: Lewis acid promoted types I and II carbonyl-ene cyclizations of 2-azetidinone-tethered alkenylaldehydes are used for the rapid, highly diastereoselective synthesis of polyfunctionalized, enantiomerically pure carbacepham derivatives. [reaction: see text]
