Photoinduced reactions of aryl-2H-azirines with carbonyl compounds. Preliminary communication

Irradiation of 3-phenyl-( 4 ), 2-methyl-3-phenyl-( 8 ), and 2,3-diphenyl-2H-azirine ( 10 ), in benzene solution in the presence of aldehydes, yields the corresponding aryl-3-oxazolines. Photochemical reaction of 4 and 10 with carbon dioxide leads to the formation of 4-phenyl- ( 15 ) and 2,4-diphenyl-3-oxazolin-5-one ( 16 ), respectively.
