摘要：

On irradiation in the presence of propen-2-yl isocyanate (4), six-membered cyclic enones 3 are converted into regio- and stereoisomeric mixtures of [2+2] cycloadducts 5-10; the preferentially formed HT products, 5-8, can be converted into the corresponding bicyclic amines by acid hydrolysis, whereas, under these conditions, the regioisomeric HH-isocyanato derivatives undergo a retro-Mannich reaction.
