(Chemical Equation Presented) Stereochemical studies of the photocycloaddition of a chiral α,β-enone and isobutylene lead to a working hypothesis for the geometry of the 3(π-π*) excited state of the enone.

A novel silver(I)-catalyzed ring-contractive rearrangement of 5-substituted 6-diazo-2-cyclohexenones has been developed, providing a new and efficient access to 5-alkylidene-2-cyclopentenones. The AgOTf-catalyzed reaction proceeds through metal-carbenoid formation followed by endocyclic allyl [1,2] migration with excellent stereoselectivity and broad substrate scope.
