Improved conditions for converting amides into 1,5-disubstituted tetrazoles are described. The optimum reaction conditions [diisopropyl azodicarboxylate (DIAD), diphenylphosphoryl azide (DPPA), and diphenyl-2-pyridyl phosphine in THF at 45 °C] converted stericallyhinderedamides to their corresponding tetrazoles in good yield.
A novel method has been developed for the synthesis of 1,5-disubstituted tetrazoles from nitrones by using bis(p-nitrophenyl) phosphorazidate in the presence of 4-(dimethylamino)pyridine. By this approach, various nitrones were converted into the corresponding tetrazoles. This method permits the preparation of 1,5-disubstituted tetrazoles without the need for toxic or explosive reagents.
