We achieved the stereocontrolled syntheses of (−)-loliolide, (−)-xanthoxin, and their stereoisomers from (+)- or (−)-3-alkoxy-6-hydroxymethyl-1,1,5-trimethylcyclohexene through the corresponding syn and anti-epoxides, respectively, which were obtained by utilizing the highly diastereoselective Sharpless asymmetric epoxidation or mCPBA oxidation.
我们通过相应的合成实现了 (-)-loliolide、(-)-xanthoxin 及其立体异构体的立体控制合成,包括 (+)- 或 (-)-3-alkoxy-6-hydroxymethyl-1,1,5-trimethylcyclohexene和抗环氧化物,它们分别是通过利用高度非对映选择性的 Sharpless 不对称环氧化或 mCPBA 氧化获得的。
