An inexpensive Ru(II) complex catalyzes the oxidative annulation reaction of disubstituted alkynes with benzamidines to provide highly valuable 1-aminoisoquinolines in high yields. The reaction also features excellent regioselectivity with some unsymmetrical alkynes.
Nickel‐Catalyzed Tandem Reaction of Functionalized Arylacetonitriles with Arylboronic Acids in 2‐MeTHF: Eco‐Friendly Synthesis of Aminoisoquinolines and Isoquinolones
example of the nickel-catalyzed tandem addition/cyclization of 2-(cyanomethyl)benzonitriles with arylboronic acids in 2-MeTHF has been developed, which provides the facile synthesis of aminoisoquinolines with good functional group tolerance under mild conditions. This chemistry has also been successfully applied to the synthesis of isoquinolones by the tandemreaction of methyl 2-(cyanomethyl)benzoates

Alkaline-metal-promoted divergent syntheses of 1-aminoisoquinolines and isoquinolines have been reported involving 2-methylaryl aldehydes, nitriles, and LiN(SiMe3)2 as reactants. In addition, the three-component reaction of 2-methylaryl nitriles, aldehydes, and LiN(SiMe3)2 has been developed to furnish 1-aminoisoquinolines. This protocol features readily available starting materials, excellent chemoselectivity
