Michael acceptors, which leads efficiently to bicyclic lactams. The process is compatible with unsymmetrical electron‐withdrawing groups on the Michael acceptor, which allows the formation of two contiguous and fully controlled tertiary and quaternarystereocenters. In the case of tetrasubstituted Michael acceptors, two adjacent quaternarystereocenters are formed in good yield. Starting from (R)‐phenylglycinol
