Palladium- and Copper-Catalyzed Solution Phase Synthesis of a Diverse Library of Isoquinolines

Abstract

The solution-phase synthesis of a 111 member isoquinoline library is described. The isoquinoline scaffold has been accessed through the palladium- and copper-catalyzed cyclization of iminoalkynes and the palladium-catalyzed iminoannulation of internal alkynes, followed by diversification of hydroxyl functionality where it is present.
