An easy and versatile access to 8-substituted isoquinolines

Lithiation of N-(2,2-diethoxyethyl)benzylamines I (R = Me, PhCH2) and reaction with electrophiles followed by acid-catalyzed cyclization leads to isoquinolines II (R1 = Me, MeO, CH2OH, MeS, Cl, Br, iodo) in 37-75% yield. [on SciFinder (R)]
