chemo- and regioselective cross-coupling reaction of the functionalized aryl triflate 5 with octylmagnesium bromide catalyzed by cheap, nontoxic, and environmentally benign Fe(acac)3 sets the basis for a practical and scaleable synthesis of the octylbenzene derivative 6, which serves as a key building block for the preparation of FTY720 (1). This 2-amino-1,3-propanediol derivative shows highly promising
的化疗和区域选择性的交叉偶联反应的官能化的芳基三氟甲磺酸酯5与辛基溴化镁以较低的,无毒的和环境友好的Fe(ACAC)催化3组的基础为辛基苯衍生物的实际和可扩展的合成6,其作为制备FTY720的关键组成部分(1)。这种2-氨基-1,3-丙二醇衍生物显示出高度有前途的免疫抑制特性,目前处于人类临床III期临床试验中。
