This paper describes a highly efficient [3 + 2] reaction between 3-vinylindoles and 3-indolylmethanols. Novel 2,3-bisindolylmethanes were prepared as single diastereoisomers in high yields with the promotion of 1 mol% 2-hydroxy-3,5-dinitrobenzoic acid.
本文介绍了 3-
乙烯基吲哚和 3-
吲哚甲醇之间的高效[3 + 2]反应。在 1 摩尔%的 2-羟基-
3,5-二硝基苯甲酸的促进下,以单非对映异构体的形式高产制备了新型 2,3-双
吲哚甲烷。
