The photochemical cyclisation of enemines has been the subject of several recent investigations, but these studies have involved N-methyl enamines (tertiary amines).ls2 We wish now to report the photochemical synthesis of 5hydroxy-3,4-dihydro-1-benzazocines (IVa -e) from enamino ketones (IIa-e) toge

Thermal, and especially photochemical, rearrangement of the endoperoxides (1) and ( )-( ) gives By-epoxycycloalkanones as primary products, accompanied by the expected syn-diepoxides. Unsaturated endoperoxides [e.g.(l)] are readily available by reaction of singlet oxygen ('0,) with conjugated diene
Irradiation of g-allqrlbenzophenones (I) results in formation of photoenols (II), which revert to the parent ketones in the dark.\* 2,5-Dimethylaaetophenone also gives a aorrespending photoenoi, but is slowly aonverted into presumably a pinacol. 3 It appeared interesting to examine photochemical beh
