An efficient Brønsted acid-catalyzed Friedel-Crafts-type alkylation of arenes with α-aryl diazoacetates has been developed. This protocol enables effective access to various highly functionalized diarylmethane derivatives in moderate to high yields. Moreover, the product of selected diaryl acetate could be transformed to β, β-diaryl substituted γ-butyrolactone.
已经开发了α-芳基重氮乙酸酯对芳烃的有效布朗斯台德酸催化的弗瑞德-克来福特型烷基化。该协议能够以中等到高收率有效地获得各种高度官能化的二芳基甲烷衍生物。而且,所选择的乙酸二芳基酯的产物可以转化为β,β-二芳基取代的γ-丁内酯。
