Substituted 3-(arylmethylene)isoindolin-1-ones can be efficiently synthesized in a stereoselective manner from various ynamides and boronic acids by palladium-catalyzed Heck-Suzuki-Miyaura domino reactions.
Synthesis of 3-(arylmethylene)isoindolin-1-ones from ynamides by Heck–Suzuki–Miyaura domino reactions. Application to the synthesis of lennoxamine
efficiently synthesized from various ynamides and boronic acids by palladium-catalyzed Heck–Suzuki–Miyaura domino reactions. This methodology has been applied to the totalsynthesis of lennoxamine and a concise route to this isoindolobenzazepinealkaloid was achieved in eight steps from 2,3-dimethoxybenzoic acid via a key intermediate ynamide.
