摘要

Abstract Ethyl 5-oxo-2-phenyl-2, 5-dihydroisoxazole-4-carboxylate (2) was photolysed at 300 nm in the presence of phenols, enols, anilines, enamines, aryl thiols and thioenols affording enamines. Treatment of these enamines with Lewis or protic acids gives the respective benzo and five-membered ring systems.
