Synthesis of new pyrroles and their biological activities.

ABSTRACT

Coumarino acid hydrazides and acid hydrazide of 2-oxy 3, 5, 6-trichloropyridine were prepared in two steps. These acid hydrazides on condensation with Acetonyl acetone i.e. 2,5-hexanedione yields new pyrroles. These pyrroles showed good to moderate antimicrobial activities against Alternaria brassicicola, Aspergillus niger, E. coli and Lactobacillus.
