An efficient method for the preparation of 2,4-disubstituted isoquinolin-1(2H)-ones is described. The reaction of α-substituted 2-lithio-β-methoxystyrenes, generated by treating α-substituted 2-bromo-β-methoxystyrenes with butyilithium, with isocyanates yields the corresponding α-substituted 2-(2-methoxyvinyl)benzamide derivatives, which in turn are transformed into 2,4-disubstituted isoquinolin-1(2H)-ones on treatment with a catalytic amount of concentrated hydriodic acid.
