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.
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.
A series of oxazolidine-based compounds with a variety of substituents in positions 2 and 3 was synthesized and their stability studied. Ring opened intermediates formed on addition of limiting amounts of D(2)O to oxazolidine solutions, as observed by NMR. As the hydrolysis reactions proceeded, a se
