An efficient Brønsted acid-catalyzed asymmetric Friedel-Crafts alkylation of indoles with benzothiazole-bearing trifluoromethyl ketone hydrates as electrophiles has been developed. The mild organocatalytic reactions proceeded well with low catalyst loading to afford a range of enantioenriched α-trifluoromethyl tertiary alcohols containing both benzothiazole and indole rings with excellent yields and
已经开发出一种有效的布朗斯台德酸与带有苯并噻唑的三氟甲基酮水合物作为亲电子试剂使吲哚的不对称弗里德-克来夫斯烷基化反应。温和的有机催化反应在低催化剂负载下进行得很好,从而提供了一系列富含苯并噻唑和吲哚环的对映体富集的α-三氟甲基叔醇,具有优异的收率和对映选择性。
