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.
罗沙汀是由多元醇链段2聚合合成的,多元醇链段2是通过砜4和醛8的朱莉娅偶联反应和多烯
膦酸酯3制备的。通过大内酯化实现环化。
