Abstract
The direct photolysis of the diester in the title compounds gave a cro ss conjugated triene, [2+2] cycloadduct, pyran, and cyclopropene. The direct photolysis of the monoester afforded a cross conjugated triene, [2+2] cycloadduct, cyclopropene, and its Z-form. The sensitized photo lysis of these esters afforded the trienes and [2+2] cycloadducts, whi ch were derived from the triplet excited state of the different chromo phores.
