(+)-Goniodiol, a potent and selective cytotoxin, and (-)-6-epi-goniodiol, as well as their enantiomers, have been synthesized starting from cinnamyl alcohol. The key steps of the synthesis were Sharpless asymmetric epoxidation and cyclization of an acrylate derivative using ring-closing metathesis reaction. The cytotoxicity of both enantiomers of goniodiol and 6-epi-goniodiol against HL-60 cells was
(+)-Goniodiol,一种有效的选择性细胞毒素,和 (-)-6-epi-goniodiol,以及它们的对映异构体,已经从肉桂醇开始合成。合成的关键步骤是使用闭环复分解反应对丙烯酸酯衍生物进行 Sharpless 不对称环氧化和环化。检查了goniodiol和6-epi-goniodiol的两种对映异构体对HL-60细胞的细胞毒性。
