Abstract: Abstract The first visible-light mediated, simple, efficient and ecofriendly protocol for the regioselective synthesis of novel [1,2,4]triazolo[3,4-b][1,3,4]thiadiazines has been developed by the reaction of α-bromodiketones, generated in situ by the bromination of a diverse array… read more here.

DOI: 10.1055/s-0036-1591991
Abstract: The synthesis of novel heterocyclic [1,2,4]triazolo[3,4-b][1,3,4]thiadiazine hybrids by a bimolecular reaction of 2-(4-amino-5-mercapto-4H-[1,2,4]triazol-3-yl)phenol with an aromatic or heterocyclic α-bromoacetyl derivatives is described. This synthetic procedure starts from an unprotected phenol. read more here.

Abstract: ABSTRACT 4-Amino-5-ethyl-4H-1,2,4-triazole-3-thiol was used as a key intermediate for the synthesis of triazolo[3,4-b][1,3,4]thiadiazines, triazolo[4,3-b][1,2,4,5]tetrazines and Schiff’s base via reactions with various hydrazonoyl halides and salicyaldehyde, respectively. Moreover triazolyl-N-N′-triazole derivatives were prepared from reaction of Schiff’s… read more here.
