Catalytic asymmetric alkynylation of 3,4-dihydro-β-carbolinium ions was developed for the versatile synthesis of enantiomerically enriched C1-alkynyl tetrahydro-β-carbolines, the utility of which was demonstrated by concise collective total syntheses of the seven indole alkaloids harmicine, geissoschizol, geissoschizine, akuammicine, desethyleburnamonine, eburnamonine, and larutensine within 10 steps
开发了 3,4-二氢-β-咔啉离子的催化不对称炔化作用,用于合成富含对映异构体的 C1-炔基四氢-β-咔啉,其效用已通过七种吲哚生物碱甘草碱的简明集体全合成证明, geissoschizol、geissoschizine、akuammicine、desethyleburnamonine、eburnamonine 和 larutensine 在 10 个步骤内(见方案)。
