Five-membered 2,3-dioxo heterocycles: LXXXVIII.* Reaction of 3-aroylpyrrolo[1,2-d][1,4]benzoxazine- 1,2,4(4H)-triones with N,N'-dicyclohexylcarbodiimide under thermolysis conditions

Thermolysis of 3-aroylpyrrolo[1,2-d][1,4]benzoxazine-1,2,4(4H)-triones generates aroyl(2-oxo-1,4- benzoxazin-3-yl)ketenes which react as dienes at the aroylketene fragment in [4 + 2]-cycloaddition at the C=N bond of N,N'-dicyclohexylcarbodiimide with form
