Abstract

Nitration of 6-substituted 2-chloro-6,7-dihydro-5H-pyrrolo[1,2-a]imidazoles was used to synthesize the corresponding 3-nitro derivatives. 6-Substituted 6,7-dihydro-5H-pyrrolo[1,2-a]imidazoles are highly selectively nitrated to the 2-position. 6-Substituted 2-amino-3-nitro-, 3-amino-2-nitro-, and 2-azido-3-nitro-6,7-dihydro- 5H-pyrrolo[1,2-a]imidazoles were synthesized. 2-Nitro-6,7-dihydro-5H-pyrrolo[1,2-a]imidazole was nitrated with a mixture of sulfuric and nitric acids to obtain 2,3-dinitro-6,7-dihydro-5H-pyrrolo[1,2-a]imidazole.
