This invention relates to a process for the production of epothilone B and derivatives as well as intermediate products for this process. In the new process, epothilone B or the derivatives are built up in high yields from the C1-C6, C7-C10 and C11-C20 fragments (2, 3 and 4) that can be obtained at a reasonable price and free of diastereomers (the variable radicals have the meanings that are indicated in the description).
本发明涉及一种生产Epothilone B及其衍
生物的过程,以及该过程的中间产物。在这个新的过程中,Epothilone B或其衍
生物可以从C1-C6,C7-C10和C11-C20片段(2、3和4)中高产率地构建而成,这些片段可以以合理的价格获得并且没有对映异构体(变量基团具有说明书中指示的含义)。
