摘要


本研究以一個典型的方法,通過三氟化硼乙醚溶液所調控的Friedel-Crafts烷基化反應,在沒有金屬錯合物的路易斯酸催化下,可以方便地得到1,1,2-三芳基乙烷及1,1-二芳基-2-烷磺基乙烷。直接引入一系列烷氧基π鍵組合物至藥物的構成中間體,包含1,2-二芳基-1-乙醇或1-芳基-2-烷磺基-1-乙醇上,是免於受到相對較長製備程序的直接合成策略。

並列摘要


In this work, a classical approach which allows an easy access to 1,1,2-triarylethanes and 1,1-diaryl-2-alkylsulfonylethanes by metal-free Lewis acid-catalysis has been carried out via BF3•Et2O-mediated Friedel-Crafts alkylation. The directly installation a series of alkoxyl π-components onto an intermediate of pharmaceutical building block which includes 1,2-diaryl-1-ethanols and 1-aryl-2-alkylsulfonyl-1-ethanols, would be a straightforward strategy without suffering from a relatively long procedure.
