friendliness, mildness, very good tolerance of functional groups, high yielding and easy experiment operation. In addition, this new methodology was successfully applied in the efficient and practical total syntheses of β-carboline alkaloids perlolyrine and flazin.
开发了一种通过Cu( II ) 催化氧化 1,2,3,4-四氢-β-咔啉 (THβCs)合成芳香族 β-咔啉的温和、高效和环保的方法,其中空气 (O 2 )用作清洁氧化剂。该方法具有环境友好、温和、官能团耐受性好、收率高、实验操作简单等优点。此外,该新方法成功应用于高效实用的β-咔啉生物碱perlolyrine和flalazin的全合成。
