Base-switched methylenation and formylation using tetramethylethylenediamine (TMEDA) as a carbon source have been achieved under mild conditions, catalyzed by CuCl(2), with atmospheric oxygen as oxidant. Bisindolylmethanes, diphenylmethanes and 3-formylindoles were synthesized with excellent regioselectivity and good yield.
使用四甲基乙二胺(TMEDA)作为碳源的碱转换的甲基化和甲酰化反应已在温和的条件下实现,由CuCl(2)催化,大气中的氧气作为氧化剂。合成了双吲哚甲烷,二苯基甲烷和3-甲酰基吲哚,具有良好的区域选择性和良好的收率。
