Abstract Propiophenone-N, N-diphenylhydrazone reacts with oxalyl chloride to give 1-diphenylamino-4-methyl-5-phenyl-2,3-dihydropyrrole-2,3-dione (1), which is isomerized at 130–140° yielding 2,3-dioxo-8, 8a-diphenyl-1, 2, 3, 3a, 8, 8a-hexahydro-3a-methyl-pyrrolo[2,3-b]indole (2). Butyrophenone-N, N-diphenylhydrazone and propiophenone-N-methyl-N-phenyl-hydrazone react in a similar way.
Notes:
Zusammenfassung Propiophenon-N, N-diphenylhydrazon reagiert mit Oxalylchlorid zum 1-Diphenylamino-4-methyl-5-phenyl-2,3-dihydropyrrol-2,3-dion (1), welches sich beim Erhitzen auf 130–140° zum 2,3-Dioxo-8,8a-diphenyl-1,2,3,3a,8,8a-hexahydro-3a-methyl-pyrrolo[2,3-b]indol (2) isomerisiert. Analog verhalten sich Butyrophenon-N, N-diphenylhydrazon und Propiophenon-N-methyl-N-phenyl-hydrazon.
