Reactions of 2-nitrophenylhydrazine and 2,4-dinitrophenylhydrazine with 2,5-dimethoxytetrahydrofuran yield the bis-hydrazones (1a) and (1b) respectively.On further heating with acid, they yield the pyrroles (2a) and (2b) respectively.Excess of 2,5-dimethoxytetrahydrofuran leads to the indoles (3a) and (3b) and the carbazoles (4a) and (4b) respectively.
