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.

✦ Synopsis
The structural elucidation of 24 xanthones with di †erent substitution patterns was performed by spectroscopic methods, namely 2D NMR techniques, such as correlation spectroscopy (COSY), nuclear Overhauser e †ect (NOE), heteronuclear correlation (HETCOR) and a 1D NMR technique, selective insensitive nuclei enhanced by polarization transfer (INEPT).

1-Aryl-4-carboxy-5-methyl-1,2,3-triazoles were prepared by the condensation of aryl azides with ethyl acetoacetate. The structures of these compounds were characterized by MS, IR and 1H and 13C NMR spectroscopy. The measured and calculated 13C chemical shifts of the aromatic carbons were compared.
A comprehensive collection of 13C chemical shifts of 159 tri-and tetracyclic quinolizidine alkaloids (sparteine derivatives) is presented. The data are discussed in terms of substituent e †ects, molecular geometries and protonation e †ects. Some IR, 1H and 15N NMR and MS data are included.
A series of acetonides was obtained during the formal synthesis of deoxynojirimycin. The 1 H NMR spectra of these derivatives contain strongly coupled multiplets covering a chemical shift range of about 1 ppm. The spectra are severely complicated by second-order effects and were assigned by 2D NMR a
