Palladium-Catalyzed C-H Oxidation of Isoquinoline N-Oxides: Selective Alkylation with Dialkyl Sulfoxides and Halogenation with Dihalo sulfoxides

A novel palladium-catalyzed C?H oxidation of isoquinoline N-oxides has been developed for regioselectively synthesizing substituted isoquinolines. The method represents the first example of using dialkyl sulfoxides as the alkyl sources for the construction of 1-alkylated isoquinolines. Moreover, the regioselective halogenation of isoquinoline N-oxides is also successful using dihalo sulfoxides as the halide sources.

EXAMPLE D 1-(5-Isoguinolinesulfonyl)-2.5-dimethylpinerazine To 40 mL of thionyl chloride is added 2,50 g of 5-isoquinolinesulfonic acid and 0.5 mL of N,N-dimethylformamide. The resulting mixture is warmed at 80 C. The volitiles are removed under reduced pressure to produce a residue. The residue is dissolved in water and the pH is adjusted to 6.0 with an aqueous sodium bicarbonate solution and the resulting mixture is extracted with methylene chloride. The methylene chloride solution is combined with a solution of 2.8 g of 1-benzyloxycarbonyl-2,5-dimethylpiperazine and 1.8 of triethylamine in methylene chloride while the mixture is maintained at 0 C. After 1 hour, the reaction mixture is allowed to warm to ambient temperature and is stirred. The reaction mixture is washed with dilute hydrochloric acid, dried (anhydrous sodium sulfate) and concentrated under reduced pressure. The residue is dissolved in methanol and 0.25 g of 5% palladium on charcoal is added. The reaction mixture is stirred at ambient temperature under a hydrogen atmosphere (40 psi). After the hydrogenolysis is complete, the reaction mixture is filtered and the filtrate is concentrated under reduced pressure. The residue is purified by column chromatography to provide 1-(5-isoquinolinesulfonyl)-2,5-dimethylpiperazine:
