collective total synthesis of tetracyclic diquinane Lycopodium alkaloids, (+)-paniculatine, (−)-magellanine, (+)-magellaninone, and two analogues (−)-13-epi-paniculatine and (+)-3-hydroxyl-13-dehydro-paniculatine, has been accomplished. By logic-guided addition of a strategically useful hydroxyl group at C-3 of paniculatine, the formidable tetracyclic core was rapidly synthesized utilizing a site-specific
四环diquinane的集体总合成石松生物碱,(+) - paniculatine,( - ) - magellanine,(+) - magellaninone,以及两个类似物( - ) - 13-外延-paniculatine和(+) - 3-羟基-13 -dehydro-paniculatine,已经完成。通过在C-3 paniculatine的战略上有用的羟基的逻辑引导另外,强大的四环核心迅速合成利用位点特异性和立体选择性醛醇环化,从而使ABD→ABCD四环方法diquinane石松生物碱可达到的第一次。
