Abstract
N-Benzoyl-N-benzylcinnamamides 1, N-acetyl-N-(1-benzyl)cinnamamides 3 and [(1-benzyl)aminocarbonyl]-N-(1-benzyl)cinnamamides 5 have been irr adiated by a high-pressure mercury lamp in the presence of benzil in b enzene at room temperature to give 3-azatricyclo[5.2.2.0(1,5)]undeca-8 ,10-dien-4-ones 2, 4 and 6 with high stereoselectivity, These are the first photo[4+2]cycloadducts of an enone and a benzene ring.
