摘要

The sensitized photooxidation of 7-methoxycycloheptatriene (7-methoxytropilidene) afforded [4+ 2] cycloadduct (2), tropone, benzaldehyde and their 2-methoxy derivatives. Thermal isomerization of 2 followed by the treatment with alumina yielded 4-methoxytropone. The photooxidation of 1-methoxytropilidene gave 4-hydroxytropone and o- methoxybenzaldehyde, and the photooxidation of 3-methoxytropilidene followed by the ...
