  Probing the SAR of dEpoB via Chemical Synthesis:  A Total Synthesis Evaluation of C26-(1,3-dioxolanyl)-12,13-desoxyepothilone B

  摘要：

  A practical total synthesis of 26-(1,3-dioxolanyl)-12,13-desoxyepothilone B (26-dioxolanyl dEpoB) was accomplished in a highly convergent manner. A novel sequence was developed to produce the vinyl iodide segment 17 in high enantiomeric excess, which was used in a key B-alkyl Suzuki merger. Subsequently, a Yamaguchi macrocyclization formed the core lactone, while a selective oxidation and a late stage Noyori acetalization incorporated the dioxolane functionality. Sufficient amounts of synthetic 26-dioxolane dEpoB were produced using this sequence for an in vivo analysis in mice containing xenograft CCRF-CEM tumors.
