The Stille coupling reaction of the stannylindole 13 with the 5-iodoimidazole derivative 14 (or 27) in the presence of PdCl2(PPh3)2 gave the corresponding indole-imidazole coupling product 15 (or 28), thereby affording a synthetic approach to 10-methylgranulatimide (7), 15-methylgranulatimide (11), and 10, 15-dimethylgranulatimide (12), as well as 10-methylisogranulatimide B (5).
斯蒂尔耦合反应中,锡取代吲哚13与5-碘咪唑衍生物14(或27)在PdCl2(PPh3)2的存在下反应,得到相应的吲哚-咪唑耦合产物15(或28),从而提供了一种合成10-甲基颗粒酰胺(7)、15-甲基颗粒酰胺(11)和10, 15-二甲基颗粒酰胺(12)以及10-甲基异颗粒酰胺B(5)的方法。
