A simple access to N-(un)substituted isoquinolin-1(2H)-ones: unusual formation of regioisomeric isoquinolin-1(4H)-ones

A ligand/additive/Pd-free Cu-mediated coupling/cyclization strategy afforded the first practical, one-pot and general approach towards synthesis of N-(un)substituted isoquinolin-1(2H)-ones. Both the catalyst and the solvent used are recyclable. The use of the Cu reagent in excess led to the unusual...

Description
Summary:A ligand/additive/Pd-free Cu-mediated coupling/cyclization strategy afforded the first practical, one-pot and general approach towards synthesis of N-(un)substituted isoquinolin-1(2H)-ones. Both the catalyst and the solvent used are recyclable. The use of the Cu reagent in excess led to the unusual formation of regioisomeric and uncommon isoquinolin-1(4H)-ones.
