Azetidinones are also formed on photolysis of cis-a-phenyl-cinnamanilide (361), but in addition a small quantity of a cis-trans mixture of 3,4-diphenyl-3,4-dihydroquinolin-2-one (362) was obtained. The yield of quinolinone was considerably increased in the photocyclization of alkyl-substituted acrylanilides.389 The anilide (363) of tiglic acid, for example, was converted into the anilide (364) of angelic acid by photochemical cis-trans isomerism, and into a mixture of cis- and [Pg.103]

The stilbene-to-dihydrophenanthrene photocyclization and the application of this reaction to nitrogen-containing systems has been reviewed in detail. Cyclization of aza-analogues of 9-styrylphenanthrene has also been reported. The related photochemical dehydrocyclization of anilides of heterocyclic car-...
