摘要

Abstract Photolysis of alkyl-substituted 2-(2-oxa-3-butenyl) cyclopent-2-enones gives rise to derivatives of bicyclo [2.1. 1] hexanes (“rule of five” product), and α- methylenecyclopentanones (photo-Claisen rearrangement). Methyl substitution remote from the bond forming centers produces a regioselective reaction yielding only the “rule of five” product.
