6-氨基-4-芳基-3-异丙基-1-苯基-4H-吡喃[2,3-c]吡唑-5-腈的三组分一锅法合成
Three Component One-Pot Synthesis of 6-Amino-4-phenyl-3-isopropyl-1-phenyl-4H-pyranopyrazol-5-carbonitrile
【摘要】 在三乙胺的催化下,以1-苯基-3-异丙基吡唑-5-酮、芳香甲醛和丙二腈三组分为原料,经一锅法合成了一系列6-氨基-4-芳基-3-异丙基-1-苯基-4H-吡喃[2,3-c]吡唑-5-腈类化合物4a~4j.与常规合成法相比,该方法具有操作简单及产率较高等优点.产物的结构通过IR,1H NMR和质谱进行了确定.
【Abstract】 A series of 6-amino-4-phenyl-3-isopropyl-1-phenyl-4H-pyranopyrazol-5-carbonitriles(4a~4j) were synthesized via three-component one-pot reaction of 3-isopropyl-1-phenylpyrazol-5-one,arylaldehydes and malononitrile under the catalysis of triethylamine.Comparing to the conventional method,the one-pot synthesis has several advantages such as simple work-up and good yield.All products were characterized by IR,1H NMR and MS techniques.
