摘要
3-取代吲哚甲胺衍生物因其多种生物活性而备受关注.吲哚与N-磺酰醛亚胺的Friedel-Crafts反应是制备3-取代吲哚甲胺衍生物的主要方法,但反应中通常会伴随大量的双吲哚甲烷化合物的生成.应用Cu(OTf)_2和脯氨亚磺酰胺共同催化吲哚与N-磺酰醛亚胺的Friedel-Crafts反应,可以选择性地合成3-取代吲哚甲胺衍生物,产率为65%~93%.该方法具有底物适用性好、反应条件温和、操作简单等优点.
3-Indolyl methanamine derivatives have attracted much attention due to their multiple potent bioactivities. The Friedel-Crafts reaction between indole and N-sulfonylaldimine is a major method for preparation of 3-indolyl methanamine derivatives, however, abundant bisindolyl methane will be formed during the reaction. 3-Indolylmethanamine derivatives were selectively synthesized in 65%~93% yields by the Friedel-Crafts amidoalkylation reaction of indoles and N-sulfonylaldimines utilizing Cu(OTf)2 and N-sulfinylprolinamide as catalysts. This method exhibited several features such as broad substrate applicability, mild reaction condition and simple operation.
