Roxaticin has been synthesized in a convergent manner. The polyol and polyene fragments were coupled by Horner-Emmons reaction and the cyclization was achieved by macrolactonization.
罗沙汀已经以收敛的方式合成。多元醇和多烯片段通过霍纳-埃蒙斯反应耦合,并且通过大内酯化实现环化。
Total synthesis of the polyene macrolide antibiotic roxaticin. II. Total synthesis of roxaticin
Roxaticin has been synthesized in a convergent manner from the polyol segment 2, which was prepared by the Julia coupling reaction of sulfone 4 and aldehyde 8, and the polyene phosphonate 3. The cyclization was achieved by macrolactonization.
