Abstract
Thermal decarboxylation of dro-4H-pyrrolo[5,1-c][1,4]benzoxazine-1,2,4 -trione resulted in 2-oxo-2H-1,4-benzoxazin-3-yl(p-toluoyl)ketene; the latter undergoes [4+2]-cycloaddition with p-bromobenzaldehyde to form -p-toluoyl-1,3-dihydro-5H-[1,3]oxazino[4,3-c][1,4] benzoxazine-3,5-di one. The crystal and molecular structure of the latter has been studie d by X-ray analysis.
