Two routes to the C1–C8 subunit of peloruside A are disclosed. The first route involving 14 steps exploits Krische's allylation, substrate controlled 1,3-asymmetric induction during bromohydrin formation from an alkene utilizing an intramolecular sulfinyl group as a nucleophile and Pummerer reaction as key steps. The second, shorter, scalable route (seven steps) exploits catalytic asymmetric reactions
公开了两种去往蛇绿苷A C1-C8亚基的途径。第一条涉及14个步骤的途径利用了Krische的烯丙基化,即在利用分子内亚磺酰基作为亲核试剂并从Pummerer反应作为关键步骤的烯烃形成溴代醇的过程中,受底物控制的1,3-不对称诱导。第二条较短的可扩展路线(七个步骤)利用催化不对称反应,其中包括Jacobsen的环氧化物水解动力学拆分和Sharpless的不对称二羟基化反应作为关键步骤。
