Research on antibacterial and antifungal agents. XIII. Synthesis and antimicrobial activity of 1-arylmethyl-4-aryl-1H-pyrrole-3-carboxylic acids.
1990
: Several 1-arylmethyl-4-aryl-1H-pyrrole-3-carboxylic acid derivatives have been synthetized and tested as antifungal and antibacterial agents. Reaction between tosylmethylisocyanide (TosMIC) and beta-arylacrylic esters under basic conditions furnished 4-aryl-1H-pyrrole-3-carboxylic esters, which were then benzylated at 1 position. Alkaline hydrolysis of ethyl 1-arylmethyl-4-aryl-1H-pyrrole-3-carboxylates afforded the title compounds. All tested derivatives were found to be inactive as antifungal agents. Some of them showed appreciable antibacterial activities against Staphylococcus spp.
