N-Benzoyl-N-benzylcinnamamides 1,
N-acetyl-N-(1-benzyl)cinnamamides 3 and
N-[(1-benzyl)aminocarbonyl]-N-(1-benzyl)cinnamamides
5 have been irradiated by a high-pressure mercury lamp in the presence
of benzil in benzene at room temperature to give
3-azatricyclo[5.2.2.01,5]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.
N-苯甲酰基-N-苄基肉桂酰胺1、N-乙酰基-N-(1-苄基)肉桂酰胺3和N-[(1-苄基)氨基羰基]-N-(1-苄基)肉桂酰胺5在室温下,在苯中存在苄基的情况下,用高压汞灯照射,得到具有高立体选择性的3-氮杂三环[5.2.2.01,5]十一碳-8,10-二烯-4-酮2、4和6。这些是烯酮和苯环的第一个光[4+2]环加成产物。
