A broad range of isoquinoline derivatives was synthesized with high chemo- and regioselectivities, via a copper-catalyzed cascade reaction of 2-haloaryloxime acetates with β-diketones, β-keto esters, and β-keto nitriles. Furthermore, this strategy provides functionalized indolo[1,2-a]quinazolines by using indoles instead of an active methylene compound.
