3-Amino-4-[5-(chloromethyl)-1,2,4-oxadiazol-3-yl]furazan - a multifunctional synthon for the synthesis of 1,2,5-oxadiazole derivatives

摘要

The chemical properties of 3-amino-4-[5-(chloromethyl)-1,2,4-oxadiazol-3-yl]furazan were scrutinized: acylation of the amino group and its oxidation to azo and nitro groups, reactions of the chloromethyl group with N- and S-nucleophilic reagents, as well as reactions of transformation of the 1,2,4-oxadiazole ring.
