PHOTOOXYGENATION OF 7-SUBSTITUTED CYCLOHEPTATRIENES

Asao, Toyonobu,Yagihara, Morio,Kitahara, Yoshio

, p. 985 - 991 (2007/10/02)

Photooxygenation of 7-substituted cycloheptatrienes, including the Me, Et, iPr, Ph, CN, COOMe, COOEt, and CONH2 groups was studied, and several products among the tropilidene-type (1 and 2) and norcaradiene-type (3 and 4) endoperoxides, o-substituted benzaldehydes (5), diepoxides (6 and 7), and ketoalcohols (8) were obtained.Mechanism of the formations of the products was discussed.Thermal isomerization of the endoperoxides (1, 3 and 4) to the corresponding diepoxides (10, 6 and 7), and the reaction of the endoperoxides (1 and 3) with triethylamine were examined.
