CuBr2-catalyzed alkylation of furans with a broad scope of benzyl alcohols and benzaldehydes is reported. Reaction proceeds efficiently under mild reaction conditions requiring no inert atmosphere or other precautions. Moreover, it is shown that CuBr2 catalyzes domino reactions of furans with benzyl alcohols or benzaldehydes bearing a nucleophilic moiety in the ortho-position. These protocols offer a
据报道,CuBr 2催化的呋喃与范围广泛的苄醇和苯甲醛的烷基化。反应在温和的反应条件下有效进行,不需要惰性气氛或其他预防措施。此外,表明CuBr 2催化呋喃与在邻位带有亲核部分的苯甲醇或苯甲醛的多米诺反应。这些协议为从易于获得的呋喃中密集取代的杂环基序提供了一种实用的方法。
