The macrodiolide antibiotic pamamycin-607 has been synthesized by coupling of the two hydroxy acid constituents using the Yamaguchi method. While the final lactonization with formation of the ester linkage between C(1) and the C(8′) oxygen proceeded with complete C(2) epimerization, the alternative ring closure involving the carboxylic acid of the smaller fragment and the hydroxyl group of the larger
通过使用山口方法将两种羟基酸成分偶联来合成大环内酯类抗生素帕马霉素-607。虽然最终的内酯化反应会在C(1)和C(8')氧之间形成酯键,但会发生完全C(2)差向异构化,但另一种闭环反应涉及较小片段的羧酸和羟基的羟基。较大的片段产生靶分子。
