  Total Synthesis of Oxazole- and Cyclopropane-Containing Epothilone A Analogues by the Olefin Metathesis Approach

  摘要：

  AbstractFor structure‐activity relationship studies, two series of epothilone A (1) analogues have been designed and synthesized, one containing an oxazole moiety instead of the thiazole heterocycle and the other containing a spirocyclopropane moiety in place of the gem‐dimethyl group at position C‐4 (4,4‐ethano‐epothilones). The olefin metathesis strategy in solution was utilized for the chemical synthesis of these compounds starting with key building blocks 7–9 for the oxazole series (compounds 2, 14–18, 21–26) and building blocks 8, 30, and 31 for the 4,4‐ethano series (compounds 3,39–43, 46–51). The convergent strategy towards the designed epothilone A series involved a) an aldol condensation reaction, b) an esterification reaction, c) an olefin metathesis reaction catalyzed by [RuCl2(=CHPh)‐(PCy3)2], and d) epoxidation of the macrocycle double bond.
