| Abstract: | 4-Hydrazino-2.5-di-tert.-Butyl-2-methyl-2H-imidazole (1) reacts with aldehydes and ketones to give condensation products (2 a-1). The reaction of1 with acyl chlorides and dicarboxylic acid chlorides gives rise to the corresponding 4-acylhydrazino-2H-imidazoles (3 a, b) and dicarboxylic-bis(imidazole-4-yl)-hydrazides (4 a-c) resp. Heating1 with acetyl bromide, ethyl orthoformate and 3-bromo-4-methyl-2-pentanone affords new condensedring systems5 a, b and7, resp. |
