✦ Synopsis

Photocycloadditions to 2-phenylbenzothiazoles proceed inhighyieldwithcertainalkmes to produce 1,5+enzothiazepines. We report herein the first exarqle of an inte.nmlecular photoadditiontiabenzothiazole inwhichasevenmnbered heterccyclic system is obtained. The cycloaddition reactions are both regiospecific md stereospecific.

## Abstract The irradiation of methyl phenylglyoxylate, benzil, benzophenone, and 1,4‐benzoquinone in the presence of homobenzvalene (3) gave products of the Paternò‐BΓΌchi reaction, i.e. the oxetane derivatives 4–8, 13 and 14, which contain a tricyclo[4.1.0.0^2,7^]heptane subunit.
