Abstract

Abstract: The stereoselectivity of the intramolecular photocycloaddition of a series of bicyclic dioxenones has been examined. The selective formation of trans-fused photoadducts is observed in almost all cases, which upon fragmentation lead to the synthesis of bicycloalkanones with an'inside-outside" or trans intrabridgehead stereochemical relationship. This methodology has been applied to the synthesis of several'inside-outside ...
