Model studies have been conducted to test several features of spirocyclization methodologies based upon excited-state reactions of allyliminium salts.Results from investigations of the photocyclization reactions of the β-enaminone-derived prenyliminium pe

Conjugated iminium salts, derived by O-alkylation or O-acylation of N-allyl β-enaminones, undergo electron-transfer-initiated photocyclization reactions leading to the production of spirocyclic amines.The yields of these processes are exceptionally high w
