Abstract

Irradiation of 1 , 4-diphenylbut-1-en-3-yne 1 and some p-quinones in dichloromethane with 300nm UV light yield tow types of adducts, i.e., p-quinomethanes and cyclobutanes, in which the former were produced via the rearrangement of the intially formed spiro-oxetene intermediates. On the other hadn 1 added to o-quinones to give three types of adducts, i.e., 1, 3-dienes, 1, 4-dioxenes, or spiro-oxetanes, in which the former were found to be applied to synthesize phenanthrene derivatives. A methoxy derivative of enyne 39 was synthesized to investigate the type of thephotoaddition to o-quinones, in which 1, 4-dioxenes were obatained.
