Synthesis of 1,4-dihydro-4-oxypyridazino[1,6-a]indole-3-carboxylic acids and 1,4-dihydro-4-oxopyrido[3',2':4,5]pyrrolo[1,2-b]-pyridazine-3-carboxyl ic acids as potential antibacterial agents

A few aza analogues of the quinolones have been prepared in the two milies of the 1,4-dihydro-4-oxopyridazino[1,6-a]indole-3-carboxylic acids and the 1,4-dihydro-4-oxopyrido[3',2':4,5]pyrrolo[1,2-b]pyridazine-3-carboxyli c acids to check their antibacterial potential. One compound 6c shows antibacterial activities of the level of nalidixic acid and represents a new lead structure differing from the classical quinolones.

A survey of several electrophilic ammonia reagents for the N-amination of indole- and pyrrole-containing heterocycles revealed that monochloramine (NH2Cl) is an excellent reagent for this transformation. Pyrroles and indoles containing a variety of substitution were aminated on nitrogen with isolated yields ranging from 45% to 97%.
