Total synthesis of thromboxane B2 using intermolecular ketalization followed by ring-closing metathesis is reported. Other key steps include a Sharpless asymmetric epoxidation to form an oxirane on the endo face of the bicyclic acetal, epoxide opening using lithioacetonitrile, an allylic alcohol 1,3-transposition, and Mitsunobu lactonization.
报道了使用分子间缩酮化然后闭环易位的血栓烷B2的全合成。其他关键步骤包括在双环缩醛的内表面上进行Sharpless不对称环氧化以形成环氧乙烷,使用硫代乙腈进行环氧化物开环,1,3-烯丙醇转位和Mitsunobu内酯化。
