✦ Synopsis

Irradiation of Z-allylcycloheptanone 3 forms a mixture of two oxetans, 4 and 2, in high yields. 11-Oxa tricycle 15.3.1 . 1'fO1 undecane 5, which constitutes The g/11 of the photoproducts, is decomposed thermally into a ?iiixture of hydroazulene derivatives. Dehydrogenation of this mixture over palladium on alumina forms azulene.
