Reactions of 1H-1,2- and 1H-1,3-Diazepines with Dimethyl Acetylenedicarboxylate

The title reactions yield the 3a,7a-dihydropyrrolopyridines (2) and 3a,7a-dihydroindazoles (9), respectively, probably via the diazonine intermediates (4) and (8) derived from the initially formed ? cycloadducts; the indazoles (9) further react with the reagent to give the dimethyl phthalates (6) and the pyrazoles (7) via the ? cycloadducts (10).
