Copper-Catalyzed sp3 C–H Aminative Cyclization of 2-Alkyl-N-arylbenzamides: An Approach for the Synthesis of N-Aryl-isoindolinones
摘要:
The synthesis of isoindolinones via copper-catalyzed sp(3) C-H functionalization of 2-alkyl-N-substituted benzamides is described. This process does not require the preparation of halogenated substitutes, expensive transition metals, or toxic Sn or CO gas. This method provides an efficient approach to generate various functionalized isoindolinones.

These HIV compounds inhibit or block the biological activity of the HIV protease enzyme, causing the replication of the HIV virus to terminate. These compounds, as well as pharmaceutical compositions that contain these compounds and optically other antiviral agents as active ingredients, are suitable for treating patients or hosts infected with the HIV virus, which is known to cause AIDS.

The present invention relates to a process for the preparation of 3-acetoxy-2-methylbenzoyl chloride by reacting an alkali metal salt of 3-aminonaph-thalene-1,5-disulfonic acid with alkali metal hydroxide and water in the weight ratio 1:(1 to 1.6):(1 to 1.6) at 220 to 320.degree. C. to give the dialkali metal salt of the 3-hydroxy-2-methylbenzoic acid, separating off insoluble constituents from the reaction mixture, then adjusting the reaction mixture to a pH of 11.5 to 13.5 by addition of acid and reacting with acetic anhydride at -5 to +25.degree. C., precipitating the 3-acetoxy-2-methylbenzoic acid by addition of acid, separating off the 3-acetoxy-2-methylbenzoic acid and reacting it with an inorganic acid chloride to give 3-acetoxy-2-methylbenzoyl chloride.
