A series of aromatic γ-hydroxyketones were prepared by means of Heck coupling reaction of aryl halides and 2,3-dihydrofuran, catalyzed by PdCl2·Gly2 and under microwave irradiation. This synthetic transformation involves the formation of an aryl-dihydrofuranoic intermediate, followed by an unusual opening of the heterocycle promoted by a water molecule and the formation of the ketone carbonyl function
在PdCl 2 ·Gly 2催化和微波辐射下,通过芳基卤化物与2,3-二氢呋喃的Heck偶联反应,制备了一系列芳族γ-羟基酮。这种合成转化涉及形成芳基-二氢呋喃基中间体,然后由水分子促进杂环的异常打开,并通过酮-烯醇互变异构作用形成酮羰基官能团。
