摘要：
Alpha,beta-unsaturated oxoesters and oxoamides bearing an alkenyl chain have been photolyzed and lead to the expected lactone and lactam cycloadducts with very high regio- and diastereoselectivity. These compounds constitute valuable precursors for spirolactones by treatement with TMS-I or polycyclic structures by reduction with Li-ammonia.
