摘要:

以邻氨基苯甲醇为原料进行催化脱氢反应,经过对催化体系的一系列筛选,最终采用[RuCl2(p-cymene)]2/AgOTf共催化体系,使邻氨基苯甲醇发生催化脱氢和芳基端炔发生交叉偶联反应,并以39%~47%的收率获得合成一系列2-芳基喹啉衍类生物,发展了邻氨基苯甲醇与芳基末端炔烃合成喹啉衍类生物的新方法,是对喹啉类衍生物合成方法的一个重要补充。

Abstract:

By using o-aminophenyl methanol as the starting material and undergoing a dehydrogenation reaction, [RuCl2(p-cymene)]2/AgOTf was finally employed as the co-catalyst system upon a systematical screening of catalysts, which enables the dehydrogenation of o-aminophenyl methanol to undergo a cross-coupling reaction with terminal aryl alkynes, affording a series of 2-aryl quinolines in 39% to 47% yields. The study has demonstrated a new method for the synthesis of quinolines from o-aminophenyl methanol and terminal aryl alkynes, which is an important complement to the synthesis of quinoline derivatives.

Key words: ruthenium catalysis, o-aminoaryl methanol, dehydrogenation, quinoline derivatives
