A convenient synthesis of 4-(1,2,3-triazolylalkyl)-1,2,3-triazole fused dihydroisoquinolines and dihydroisoindoles is reported, starting from easily available (2-iodoaryl)alkyl azides and terminal alkynols. The procedure is based upon transition-metal catalyzed coupling reactions followed by iterative cycloaddition reactions.
据报道,从容易获得的(2-碘芳基)烷基叠氮化物和末端炔醇开始,方便地合成4-(1,2,3-三唑基烷基)-1,2,3-三唑稠合的二氢异喹啉和二氢异吲哚。该程序基于过渡金属催化的偶联反应,然后进行迭代的环加成反应。
