Synthesis of 3-Pyrazolyl-1,2,4-Triazoles via One-Pot Multicomponent Reaction in Phosphoric Acid
A high-yielding synthetic route towards pyrazolyl-[1,2,4]triazole derivatives has been developed via one-pot multicomponent reaction of polyfunctionalized triazoles, DMF-DMA, acetophenone, ethyl cyanoacetate, and/or 3-oxo-3-phenylpropanenitrile in _ortho_-phosphoric acid (85%). In the same manner, a new series of 2-triazolyl-tetrahydro-indazol-4-ones and pyrazolo[3,4-_d_]pyrimidines has been synthesized by reaction of triazoles, DMF-DMA and 1,3-cyclohexanediones and/or barbituric acid, respectively. The same products were prepared a classical manner ... إقراء المزيد
