Irradiation of 1-acetyl-1,2-dihydroquinoline-2-carbonitrile (1) in ether gave the 3,1-benzoxazine (3b), while the 4-methyl congener (2) in either ether or ethanol gave the 3,1-benzoxazine (4b) and the cycloprop[b]indole (7). A possible mechanism for the formation of these products is also discussed.
