摘要：

The total synthesis of a family of (E)-9,10-dehydro derivatives of epothilone D (i.e., 12,13-desoxyepothilone B) is described. The route is particularly concise and amenable to production of new congeners. Furthermore, the chemistry described herein constitutes a major simplification in the total synthesis of EpoD, which is in human clinical trials. This new family of epothilones shows major advantages in terms of their potency and pharmacostability relative to the wild-type saturated analogues in the D series. From the perspective of compound availability through synthesis, potency, and pharmacokinetic properties, these compounds could well warrant advancement to clinical evaluation in humans.
