AbstractรWhile intermolecular photocycloaddition of alkenes with 2-carboxamidocyclo-2-pent-1-enones was not an efยฎcient process, photolysis of 2-alkenylcarboxamido-2-cycloalken-1-ones led regio-and stereospeciยฎcally to a faster [212] intramolecular reaction and therefore to the corresponding cyclobu
