The acid catalyzed condensation of 4,5-diaminopyrazoles and chalcones gave the hitherto unknown 1-benzyl-2,4,6-triphenyl-2,3-dihydropyrazolo[3,4-b][1,4]diazepines derivatives. The structure of all products was supported by ir, 1H and 13C-nmr and mass spectra.
4,5-二氨基吡唑和查耳酮的酸催化缩合反应产生了迄今未知的1-苄基-2,4,6-三苯基-2,3-二氢吡唑并[3,4- b ] [1,4]二氮杂卓衍生物。ir,1 H和13 C-nmr和质谱支持所有产物的结构。
