## 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.
A series of 14 3-substituted 4-oxoquinolones with or without a substituent (methyl, ethyl) in position 1 were prepared. Literature and measured data were used to study the inÑuence of the substituent on the shifts of carbon atoms of these compounds, which are model compounds for antibacterial drugs
Jordan 1,3,5-Tris(5-substituted-1,3,4-oxadiazol-2-yl)benzenes were prepared by the dehydration of the corresponding hydrazides. The structures of these compounds were elucidated by IR, 1H and 13C NMR spectroscopy.
## Abstract Dehydration of __N__,__N__′‐diacylalkanedioic acid dihydrazides with phosphoryl chloride gave 5,5′‐disubstituted‐2,2′‐(1,__n__‐alkanediyl)bis‐1,3,4‐oxadiazoles. The structures of these compounds were elucidated by ^1^H, ^13^C NMR, UV and IR spectroscopy.
## Abstract Some novel 1, 2, 4‐triazolo[3,4‐__b__][1,3,4]thiadiazines derivatives 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, HMBC, and HSQC. Copyright © 2006 John Wiley & Sons,
