A new synthetic route to isoquinolin-1(2H)-one derivatives from 3-hydroxyphthalides

Sugimoto,Shinba-Tanaka,Ishikawa

, p. 431 - 434 (2007/10/02)

A new synthetic route for the conversion of substituted 3-hydroxyphthalides into the corresponding isoquinolin-1(2H)-one was established. This method can be applied to the preparation of isoquinolin-1(2H)-ones with electron-withdrawing groups that are relatively difficult to synthesize by conventional procedures.
