A three-component reaction of (E)-2-ethynylphenylchalcone, sulfonyl azide, and amine catalyzed by copper(I) chloride (5 mol%), in the presence of triethylamine, under mild conditions is described. This transformation proceeds efficiently to generate 1,2-dihydroisoquinolin-3(4H)-imines in good to excellent yields.
描述了在温和的条件下,在三乙胺的存在下,由(I)-2-乙炔基苯基查耳酮,磺酰叠氮化物和由氯化铜(I)(5 mol%)催化的胺的三组分反应。该转化有效地进行,以良好的至优异的产率产生1,2-二氢异喹啉-3(4H)-亚胺。
