DMP 323, a potent HIV-1 protease inhibitor, has been synthesized by an efficient stereoselective process, amenable to large scale preparations. The core C(2) symmetric diol was synthesized by a stereoselective pinacol coupling of CBZ protected D-phenylalanine. Judicious selection of protecting groups allowed cyclic urea formation under mild conditions, enhanced the ease of bis-alkylation, and led to
DMP 323是一种有效的HIV-1蛋白酶抑制剂,已经通过有效的立体选择性方法合成,适用于大规模制备。核心的C(2)对称二醇是由CBZ保护的D-苯丙氨酸的立体选择性频哪醇偶联合成的。明智地选择保护基团可以在温和条件下形成环状脲,增强了双烷基化的难度,并导致了无需色谱即可轻松纯化的中间体。另外,开发了一种单锅高产率方法,以从1,4-苯二甲醇制备烷基化剂4-[((三苯基甲氧基)甲基]苄基氯。
