Nitrofuranyl heterocycles. XIIIN‐methyl‐3‐methylthio‐5‐(5‐nitro‐2‐furanyl)‐1H‐1,2,4‐triazoles

Abstract

A continuing search for new nitrofurans which might possess useful antimicrobial activity led to the synthesis of several 3‐mercapto‐5‐(5‐nitro‐2‐furanyl)‐1H‐1,2,4‐triazoles and their methylated derivatives. This paper describes the preparation of these compounds together with proof of structure of the N‐methylated products.

The chemistry of mercapto- and thione- substituted 1,2,4-triazoles and their utility in heterocyclic synthesis

“…The alkylation of 75 with methyl iodide or 4-(chloroacetyl/α-chloropropionyl)-2,3-dihydropyrazoles 175 in alkaline medium resulted in the production of the S-alkylated derivatives 174 105 and 176 …”
