## Abstract 4‐Amino‐5‐substituted aryl‐3‐mercapto‐1,2,4‐triazoles are versatile synthons for constructing various biologically active heterocycles. Starting from 4‐amino‐5‐substituted aryl‐3‐mercapto‐1,2,4‐triazole **3a**–**c**, a series of new 3,5‐disubstituted‐1,2,4‐triazolo‐[3,4‐__b__]1,3,4‐thia
A series of 4-(alkylidene/arylidene)amino-5-(2-furanyl)-2.4-dihydro-3H-I .2.4-triazolc-3-1hiones (2) and 6-aryl-3-(2-furanyl)-7H-12.4-triazolo[3,4-b]( 1.3.41 thiadiazines (3) werc synthesized. The configuration of 2g was assigned on che basis of 'H-NMR data. Of the new derivatives tesced. only 2b. 2
Novel 6-aryl-3-[5-methyl-1-(4-methylphenyl)-1,2,3-triazol-4-yl]-s-triazolo[3,4-b]-1,3,4-thiadiazoles were synthesized by the condensation of 3-[5-methyl-1-(4-methylphenyl)-1,2,3-triazol-4-yl]-4amino-5-mercapto-s-triazole with various aromatic carboxylic acids in the presence of phosphorus oxychlorid
