A novel, facile, and expeditious two-step synthesis of 3,4-unsubstituted isoquinolin-1(2H)-ones from a Suzuki cross-coupling between 2-halobenzonitriles and commercially available vinyl boronates followed by platinum-catalyzed nitrile hydrolysis and cyclization is described.

Hepatitis C virus inhibitors are disclosed having the general formula:(I) wherein R1, R2, R3, R', B, Y and X are described in the description. Compositions comprising the compounds and methods for using the compounds toinhibit HCV are also disclosed.
A simple and efficient method for the synthesis of isoquinolone and isocoumarin derivatives is reported. The method for the first time provides a one-step divergent synthesis of important isoquinolone and isocoumarin skeletons from benzoicacid by switching the coupling partners. In addition, a reliable mechanism has been proposed on the basis of experimental investigations, including kinetic isotope

conditions was described. These methods provide an alternative and facile synthetic route to access a series of 4‐arylthio‐substituted isoquinolin‐1(2H)‐one derivatives in moderate to good yields. This is a useful, time‐efficient, and scalable procedure for the construction of C(sp2)−S bonds.
isoquinolin-1(2H)-ones at the C-4 position is reported by employing ethyl sulfinates, and the corresponding products are obtained in moderate to excellent yields in the presence of iodine. This synthetic strategy provides a range of thioether-isoquinolin-1(2H)-ones while tolerating a number of functional groups on the isoquinoline nitrogen atom and benzene ring. In addition, pyridin-2(1H)-one is also reacted
