A concise total synthesis of enantiopure (+)-preussin (1) from L-phenylalanine (3) is described. The key steps involve i) syn-selective formation of the 1, 2-amino alcohol fragment2, via chelation controlled addition of allylmagnesium bromide toN-Boc-phenylalaninal, and ii) L-selectride® mediated stereoselective reduction of the ketone8 to the alcohol derivative9 with the required stereochemistry for
描述了从L-苯丙氨酸(3)的简明全合成对映体(+)-普鲁酶(1)。的关键步骤涉及ⅰ)顺式的1,2-氨基醇片段-选择性形成2,通过螯合控制地加入烯丙基溴化镁吨-BOC-苯基丙氨酸,和ii)L-selectride®介导的酮立体选择性还原8到具有最终环化所需的立体化学的醇衍生物9。
