The practical syntheses of pachastrissamine (jaspine B), 2-epi-pachastrissamine, and the 2-epimer of the pyrrolidine analogue were accomplished via the stereoselective reduction of an allylketone derived from commercially available diethyl D-tartrate and the cross-metathesis of an allyltetrahydrofuran or allypyrrolidine with 1-tridecene as key steps.
通过来自商业可得的二乙基D-酒石酸盐的烯丙基酮的立体选择性还原,以及烯丙基四氢呋喃或烯丙基吡咯烷与1-三癸烯的交叉 метатезis,成功合成了pachastrissamine(jaspine B)、2-epi-pachastrissamine及其吡咯烷类似物的2-表异构体。
