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