The total syntheses of three marine bis-indole alkaloids (1, 2, 4) of the topsentin family together with the synthesis of the unnatural deoxybromotopsentin (33) are described. Key elements include, a 1,2-addition-oxidation sequence to construct the bis-heteroarylketones (18, 19, 29, 30) and a Pd-catalyzed heteroarylation involving the 3-stannylindoles (12, 26)
描述了托普汀家族的三种海洋双吲哚生物碱(1、2、4)的总合成以及非天然脱氧溴青霉素(33)的合成。键元件包括1,2-加成氧化序列来构造双- heteroarylketones(18,19,29,30),并涉及3- stannylindoles一个Pd催化的杂芳基化(12,26)
