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.
开发了一种在4-(二甲氨基)吡啶存在下使用叠氮化双(对硝基苯基)磷酸酯从硝酮合成1,5-二取代四唑的新方法。通过这种方法,各种硝酮转化为相应的四唑。该方法允许制备 1,5-二取代四唑,而不需要有毒或爆炸性试剂。
