The formal total synthesis of epothilone A is described. The 3 is formed by introduction of the thiazole moiety by a Wittig reaction and subsequent functional group transformation. An key steps in the synthesis of the northern hemisphere are a Z-selective ten-membered ring-closing metathesis reactio
