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.
