The stereoselective syntheses of diastereomers of antitumor natural pericosine A from (-)-quinic acid were achieved. One of the diastereomers, methyl (3 R,4 S,5 S,6 R)-6-chloro-3,4,5-trihydroxycyclohex-1-enecarboxylate, possesses the reported structure of pericosine A. The reported relative configuration of natural pericosine A was shown to be incorrect.
实现了以(-)-奎尼酸为原料立体选择性合成抗肿瘤天然Pericosine A的非对映异构体。其中一种非对映异构体甲基 (3 R,4 S,5 S,6 R)-6-chloro-3,4,5-trihydroxycyclohex-1-enecarboxylate 具有已报道的 pericosine A 结构。 pericosine A 被证明是不正确的。
