Lewis acid-assisted ene cyclization of 2-azetidinone-tethered enals: Synthesis of enantiopure carbacepham derivatives

Diastereocontrolled Lewis acid-catalyzed preparation of enantiopure carbacepham derivatives have been developed starting from 2-azetidinone-tethered enals. The BF3.Et2O-promoted reaction of alkenylaldehydes 1 and 16 is effective as c

Rapid entry to enantiopure carbacepham derivatives via Lewis acid promoted carbonyl-ene cyclization of 2-azetidinone-tethered alkenylaldehydes

(Matrix Presented) 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.
