Reaction of Benzocinnolinium-5-(N-acyl- and N-benzimido-imides) with Diphenylcyclopropenone

Barr, John J.,Storr, Richard C.,Tandon, Vishnu K.

, p. 1147 - 1149 (1980)

Benzocinnolinium-5-(N-acylimides) (6; R = Ph, OEt, or Me) give benzocinnoline and 2-substituted-4,5-diphenyloxazin-6-ones (7) on reaction with diphenylcyclopropenone.In contrast, the related benzocinnolinium-5-(N-benzimidoimides) (11; R = H, Ph, or p-tolyl) give stable adduct (12), which on pyrolysis yield benzocinnoline and 1-substituted-2,5,6-triphenylpyrimidin-4-ones.
