Abstract
Five 5‐substituted‐4‐(arylidene)amino‐2,4‐dihydro‐3__H__‐1, 2,4‐triazole‐3‐thiones (2a–2e) and seven 6‐aryl‐3‐(D‐gluco‐pentitol‐1‐yl)‐7__H__‐1,2,4‐triazolo[3,4‐b][1,3,4]thiadiazines (3a–3g) were synthesized. The complete ^1^H and ^13^C NMR chemical shift assignments were analyzed on one‐ and two‐dimensional NMR techniques, including DEPT, NOE‐DIF, COSY, gHMBC, and gHSQC.

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
The reaction of 3-mercapto-4-aryIideneamino-l,2,4triazoles 2b-d, 3a-d with ethyl bromoacetate and/or phenacyl bromide in hot DMF and triethylamine affords the stereochemically pure 7-acyl-6-aryl-6,7dihydro-5H-lt2, 4-triazolo[3,4-b][l, 3,4]thiadiazines
## Abstract Ten new 1,2,4‐triazolo[3,4‐__b__]‐1,3,4‐thiadiazole derivatives were synthesized and their NMR spectra were analyzed by 1D and 2D NMR techniques (gCOSY, gHMBC, gHMQC). Copyright © 2001 John Wiley & Sons, Ltd.
