Abstract: A simple and efficient protocol has been described for the synthesis of [1,2,4]triazolo[4,3-a]pyri-dines and 3,5-disubstituted-1,2,4-oxadiazoles by reacting 2-hydrazinylpyridine and benzamidoximes, respec-tively, with styrenes via TBAI/TBHP-mediated oxidative cleavage of C=C bond under ligand- and metal-free conditions.

The analogous three-component synthesis strategy for substituted 1,2,4-oxadiazole and quinazoline derivatives from readily available benzaldehyde, benzylamine and hydroxylamine or aniline has been developed. Both the cascade reaction sequences involves nucleophilic addition of C?N bond, introduction a halogen donor, nucleophilic substitution and Cu(II)-catalyzed aerobic oxidation. This synthesis methodology demonstrated good yields, broad substrate scope and oxygen as a green oxidant. Thus, this synthesis protocol provides strategies for the construction of substituted 1,2,4-oxadiazole and quinazolines from readily and simple starting materials. (Figure presented.).
