An efficient and convergent four-step synthetic route to the CXCR4 chemokine receptor antagonist AMD070 (1) has been developed which employs only a single chromatographic step in the entire sequence. Novel reductive amination methods have been developed for the coupling of 2 and 3 in which a dehydrative imine formation is followed by reduction with an attenuated borohydride reagent (zinc chloride and
已经开发了一种有效且收敛的四步合成路线,可合成CXCR4趋化因子受体拮抗剂AMD070(1),在整个序列中仅使用一个色谱步骤。已经开发了用于2和3的偶联的新型还原胺化方法,其中脱水亚胺的形成随后是用减毒的硼氢化物试剂(氯化锌和硼氢化钠)还原。采用选择性提取方法纯化合成中间体并去除试剂和杂质。的过程也被开发以隔离1在纯结晶形式。
