Present work demonstrates a facile synthesis of a series of 20 dihydropyrazole derivatives from well designed curcumin analogues by reaction of chalcone derivatives with phenylhydrazine. All the synthesized compounds were characterized by spectroscopic (1H and 13C NMR, IR spectra), spectrometric (Mass spectra) data and elemental analysis. Synthesized dihydropyrazoles have diversity points on attached
目前的工作表明,通过查耳酮衍生物与苯肼的反应,可以从精心设计的姜黄素类似物中轻松合成一系列 20 种二氢吡唑衍生物。所有合成的化合物均通过光谱(1H 和 13C NMR、IR 光谱)、光谱(质谱)数据和元素分析进行表征。合成的二氢吡唑在连接的苯环上具有多样性点。根据苯环上基团产生的电子效应来解释取代基对反应性的影响。二氢吡唑的 1H NMR 谱中 dd(双峰)的存在也被解释为由于吡唑环中光学活性碳的存在。
