Substituent Effect on the regio and stereoselectivity of [2+2]photocycloaddition of furans with cyclic enones

Abstract

Mechanistic and sysnthetic studies have been performed in the photochemical [2+2] cycloaddition reaction of cyclic enones with alkenes. Strained and synthetically useful cyclobutane structure can be synthesized using the photochemical reaction in one step. In this present study, the regio- and stereoselectivity were investigated in the photochemical cycloaddition reactions of cyclopentadiene with furan derivatives, in detail.
