The stereoselective synthesis of the spiroketal fragment 4a and its C1″-epimer 4b of the HIV-1 protease inhibitors didemnaketals has been carried out through multisteps from the natural (R)-(+)-pulegone, which involved the diastereoselective construction of four chiral carbon centers by intramolecular chiral induction.
HIV-1蛋白酶抑制剂ditemnaketals的spiroketal片段4a及其C1“ -epimer 4b的立体选择性合成已通过天然(R)-(+)-pulegone的多步反应完成,其中涉及四个手性的非对映选择性通过分子内手性诱导形成碳中心。
