of simplified bryostatin analogues are synthesized through an optimized esterification–macrotransacetalization strategy. This family incorporates both an ester linkage between C5 and C9 in addition to a C9 t-butyl substituent to mimic the bryostatin A-ring. Importantly, a free C7 alcohol is revealed late in the synthesis, allowing access to numerous C7 derivatized analogues.
通过优化的酯化-宏观反缩醛化策略合成了简化的苔藓抑素类似物新家族的第一个生物活性成员和关键中间体。该家族除C9叔丁基取代基外还结合了C5和C9之间的酯键,以模拟bryostatin A-环。重要的是,在合成后期发现了游离的C7醇,从而可以使用多种C7衍生的类似物。
