The first total synthesis of the boron-containing macrodiolide antibiotic tartrolon B is reported in full detail. Two convergent approaches to the target compound are described, the first of which eventually failed, due to sensitive functionality. In the second, successful route the key step was a stereoselective boron-mediated aldol addition of a bicyclic acetonide protected ketone to a diene-aldehyde
详细报道了含硼的大乙交酯抗生素tartrolon B的第一个全合成。描述了两种针对目标化合物的融合方法,由于敏感的功能,第一种方法最终失败。在第二条成功的途径中,关键步骤是将双环丙酮化物保护的酮立体选择性地由硼介导的羟醛加成到二烯醛中。在这种情况下,使用Yamaguchi二聚化大内酯化残基可以完成合成而没有重大问题。
