efficiently synthesized from various ynamides and boronic acids by palladium-catalyzed Heck–Suzuki–Miyaura domino reactions. This methodology has been applied to the total synthesis of lennoxamine and a concise route to this isoindolobenzazepine alkaloid was achieved in eight steps from 2,3-dimethoxybenzoic acid via a key intermediate ynamide.
可以通过钯催化的Heck–Suzuki–Miyaura多米诺反应,从各种酰胺和硼酸中高效合成取代的3-(芳基亚甲基)异吲哚啉-1-酮。该方法已应用于伦诺沙明的总合成,并通过关键的中间体酰胺从8,3个步骤以简明的路线制备了该异吲哚并苯并ze庚因生物碱。
