The total synthesis of a family of (E)-9,10-dehydro derivatives of epothiloneD (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
描述了埃坡霉素 D 的 (E)-9,10-脱氢衍生物家族(即 12,13-脱氧埃坡霉素 B)的全合成。该路线特别简洁,适合生产新的同类物。此外,本文描述的化学构成了 EpoD 全合成的主要简化,这是在人类临床试验中。相对于 D 系列中的野生型饱和类似物,这个新的埃坡霉素家族在其效力和药物稳定性方面显示出主要优势。从通过合成、效力和药代动力学特性的化合物可用性的角度来看,这些化合物很可能保证推进人类临床评估。

The invention comprises a novel process for the preparation of an epothilone derivative of formula I:
wherein R
1
and R
2
independently from each other represent hydrogen or protecting groups and R
3
is methyl or trifluoromethyl, which are useful precursors in the synthesis of the desoxyepothilone derivatives of the formula IV:
wherein R
3
is methyl or trifluoromethyl. The desoxepothilones of formula IV inhibit the growth of tumor cells and are therefore promising candidates for novel anticancer agents.

The invention relates to a novel process for the preparation of an epothilone derivative of the formula (I) wherein R1 and R2 are silyl protecting groups, that uses a sultam alcohol of the formula (IV) wherein R is hydrogen or lower alkyl and R1 is a silyl protecting group, as intermediate. The compound of formula (I) is useful for the preparation of desoxyepothilones that are promising candidates for novel anticancer agents.
