A wide variety of substituted isoquinolin-1(2H)-ones were synthesized in reasonable to good yields by the palladium-catalyzed cyclization of diethyl(2-iodoaryl)malonates with imidoyl chlorides and carbon monoxide in tetrahydrofuran. A palladium-catalyzed carbonylation-decarboxylation process may be involved in the one-step synthesis of the isoquinolin-1(2H)-ones.
Synthesis of Highly Substituted Isoquinolone Derivatives by Nickel-Catalyzed Annulation of 2-Halobenzamides with Alkynes
An efficient method for the synthesis of substituted 1(2H)-isoquinolone derivatives via nickel-catalyzed annulation of substituted 2-halobenzamides with alkynes is described. This protocol is successfully applied to the total synthesis of oxyavicine with excellent yield.
