Reaction of different substituted indoles with acetone was investigated using Bi(OTf)3 as a catalyst. An efficient protocol was developed for the synthesis of spiro indoles, 1-methyl-cyclopenta[b]indole and bis(1-methyl-1H-indolyl)propanes via the reaction of indole with acetone in the presence of Bi(OTf)3. The reaction conditions were benign, required shorter reaction time, and gave good yields.
采用Bi(OTf)3作为催化剂,研究了不同取代吲哚与丙酮的反应。开发了一种高效合成螺吲哚、1-甲基-环戊[b]吲哚和双(1-甲基-1H-吲哚基)丙烷的方法,通过在Bi(OTf)3存在下吲哚与丙酮反应实现。该反应条件温和,反应时间短,产率高。
