preparation of tetrahydroquinolines has been developed. The procedure involves a highly regio-and enantioselective intermolecular iridium-catalyzed allylic amination followed by one-pot hydroboration and intramolecular Suzuki-Miyaura cross-coupling. This method was applied in total syntheses of the alkaloids (+)-angustureine and (-)-cuspareine.
已开发出一种用于制备四氢喹啉的无保护基团的两步法。该过程涉及高度区域和对映选择性的分子间铱催化烯丙基胺化,然后是一锅硼氢化和分子内 Suzuki-Miyaura 交叉偶联。该方法应用于生物碱(+)-茴香碱和(-)-cuspareine的全合成。
