The first enantioselective construction of a new class of axially chiral naphthyl-indole skeletons has been established by organocatalytic asymmetric coupling reactions of 2-naphthols with 2-indolylmethanols (up to 99 % yield, 97:3 e.r.). This approach not only affords a new type of axially chiral heterobiaryl backbone, but also provides a new catalytic enantioselective strategy for constructing axially chiral biaryl scaffolds by making use of the C3-electrophilicity of 2-indolylmethanols.
通过 2-萘酚与 2-吲哚甲醇的有机催化不对称偶联反应,首次建立了一类新型轴手性萘基-吲哚骨架的对映选择性构建方法(最高产率 99%,97:3 e.r.)。这种方法不仅提供了一种新型的轴手性杂芳基骨架,而且通过利用 2-吲哚甲醇的 C3-亲电性,为构建轴手性联芳基支架提供了一种新的催化对映选择性策略。
