palladium‐catalyzed CHoxidation of isoquinoline N‐oxides has been developed for regioselectively synthesizing substituted isoquinolines. The method represents the first example of using dialkylsulfoxides as the alkyl sources for the construction of 1‐alkylated isoquinolines. Moreover, the regioselective halogenation of isoquinoline N‐oxides is also successful using dihalosulfoxides as the halide sources

A base-controlled [3+3] cycloaddition reaction of isoquinolineN-oxides with azaoxyallyl cations is developed. 1,11b-Dihydro-[1,2,4]oxadiazino[3,2-a]isoquinolin-2(3H)-ones are obtained when isoquinolineN-oxides are treated with [small alpha]-halohydroxamates in the presence of sodium carbonate, while...

A straightforward method for direct decarboxylative arylation of 1- and 3-carboxy isoquinaldic acid N-oxides with aryl iodides is reported. The reaction proceeded selectively at the carboxy function site to exclusively give the corresponding C-(1) or C-(3) arylated product. This methodology tolerates various aryl iodides substituted by electronically different groups. Combined with subsequent Reissert-Henze chlorination and SNAr amination, the decarboxylative arylation provides an efficient access to 1,3-functionalized isoquinoline-based antitumor agent.
