A simple, convenient and practical protocol to synthesise 5-substituted1H-tetrazoles from alcohols or aldehydes is reported. Using ammonia and sodium azide as nitrogen sources and Cu(NO3)2 as catalyst, benzylic alcohols and benzaldehydes were directly converted into 5-substituted1H-tetrazoles in a one-pot procedure.

antibacterial properties of certain tetrazole derivatives have been described. We have previously reported the antibacterial properties of aryl 1Htetrazole compounds. Objective: To study the antibacterial activity of 5-substituted heteroaryl, vinyl, benzyl, and alkyl 1H-tetrazole derivatives. Methods: The antibacterial properties of heteroaryl, vinyl, benzylic, and aliphatic tetrazole derivatives were investigated

The addition of sodium azide to nitriles to give 1H-tetrazoles is shown to proceed readily in water with zinc salts as catalysts. The scope of the reaction is quite broad; a variety of aromatic nitriles, activated and unactivated alkyl nitriles, substituted vinyl nitriles, thiocyanates, and cyanamides have all been shown to be viable substrates for this reaction.

It has been discovered that inhibiting mitochondrial respiration in platelets reduces platelet activation or platelet aggregation. Certain heterocyclic compounds significantly reduced one or more platelet functions including clumping, sticking or platelet-stimulated clotting. Thus diseases or disorders mediated by inappropriately high levels of platelet activation or platelet aggregation can be treated by administering a therapeutically effective amount of a heterocyclic compound or nonheterocyclic mitochondrial inhibitor that significantly reduces one or more platelet functions including clumping, sticking or platelet-stimulated clotting, preferably in a reversible manner.
Abstract An efficient one-step method for the synthesis of 5-substituted 1H-tetrazoles from aldehydes by reaction with acetohydroxamic acid and sodium azide using bismuth(III) triflate as the catalyst is described.
