Palladium-Catalyzed Regioselective Heck–Suzuki–Miyaura Cascade Cyclization for the Synthesis of Trisubstituted Arylideneisoquinolinones.

An Ugi four-component reaction was used to construct propargylamide starting materials for a subsequent domino Heck–Suzuki–Miyaura cross-coupling reaction to give derivatives of 4-benzylidene-1-oxo-3,4-dihydro-1 H -isoquinoline. [ABSTRACT FROM AUTHOR]
