title: Studies of the stereochemistry of [2+2]-photocycloaddition reactions of 2-cyclohexenones with olefins.
abstract: Stereochemical studies of the photocycloaddition of a chiral alpha,beta-enone and isobutylene lead to a working hypothesis for the geometry of the 3(pi-pi*) excited state of the enone. [reaction: see text]
