catalytic activation of the leaving group in the S(N)2 reaction is achieved as an extension of our mercuric triflate-catalyzed reactions. Derivatives of anilinoethyl 4-pentynoate reacted smoothly with catalytic amounts of Hg(OTf)(2) to give indoline derivatives in excellent yield with efficient catalytic turnovers under very mild conditions. The reaction of optically pure secondary alcohol derivatives
作为我们的三氟甲磺酸汞催化反应的扩展,实现了S(N)2反应中离去基团的新型催化活化。4-戊戊酸苯胺基乙酯的衍生物与催化量的Hg(OTf)(2)平稳反应,可在非常温和的条件下以优异的收率得到高效的二氢吲哚衍生物。光学纯仲醇衍生物的反应导致立体化学的转化,这是S(N)2反应的确定特征。该程序适用于苯并ze庚因的合成。
