A site-selective C-4/C-8 alkynylation of isoquinolones catalyzed by gold and rhodium complexes is reported. A broad range of synthetically useful functional groups (−F, −Cl, −Br, −CF3, −OMe, alkyl, etc.) were tolerated, providing an efficient and robust protocol for the synthesis either C-4- or C-8-alkynylated isoquinolones.

Said compositions and methods are useful for the treatment of cancer and neoplastic disease.
A general and efficient procedure for p-toluenesulfonic acid-catalyzed iodination of isoquinolin-1(2H)-ones with N-iodosuccinimide at room temperature is described. This method provides an alternative way of constructing C–I bonds, affords various 4-iodoisoquinolin-1(2H)-ones in moderate to good yields, and shows a broad substrate scope and good functional group tolerance.

A new, selective Ru(II)-catalyzed alkynylation reaction of isoquinolones, quinazolones and phthalazinones with readily available bromoalkynes has been developed. This reaction enables the selective construction of a new C(sp2)-C(sp) bond through C—Hactivation and C—Br functionalization, and offers an effective and selective route to synthesizing highly valuable alkynylated isoquinolone, quinazolone
