Prenylated indole alkaloids bearing more than one prenyl or reverse-prenyl group show various biological activities. Among them, synthesis of trisubstituted-type prenylated indoles have not been well explored because of the difficulty in regioselective introduction of multiple prenyl and reverse-prenyl groups due to steric hindrance problems. Herein, we describe a synthesis of 2,6,7-trisubstituted prenylated indole using aza-Claisen rearrangement under mild conditions to introduce a prenyl group at C7 in the presence of the prenyl group at C6.

2,6,7-三取代的炔丙基吲哚的合成

带有一个以上异戊烯基或反向异戊烯基的炔丙基吲哚生物碱具有多种生物活性。其中,由于空间位阻问题,由于难以将多个异戊烯基和反异戊烯基基团进行区域选择性引入,所以尚未很好地探索三取代型炔丙基化吲哚的合成。在本文中,我们描述了在温和条件下使用氮杂-克莱森重排在C6异戊烯基存在的情况下在C7引入异戊二烯基的合成2,6,7-三取代的炔丙基吲哚的方法。
