Intermolecular [2+2] photocycloaddition of a variety of alken- and alkyn-3-ols with 3,4,5,6-tetrahydrophthalic anhydride (THPA) and the related imide (THPI) gave the corresponding cyclobutanes and cyclobutenes in high yield. Irradiation times were relatively short and stereoselectivities as high as for the cyclobutane examples.
