Abstract

A two-step isoindolone synthesis has been achieved by using an Ugi/oxidative vicarious nucleophilic substitution sequence starting from 3-nitrobenzoic acid and aromatic aldehydes. Loss of the amido group was observed as well as a further oxidative process towards hydroxyisoindolone derivatives after prolonged stirring open to the atmosphere.

  • 15 Typical Procedure for the Ugi/Oxidative VNS for 1a/2a To a solution of 4-chlorobenzaldehyde (281 mg, 2.0 mmol) in MeOH (2 mL) were added successively n-butylamine (0.19 mL, 2.0 mmol), 3-nitrobenzoic acid (334 mg, 2.0 mmol), and tert-butyl isocyanide (0.22 mL, 2.0 mmol). The resulting mixture was stirred at rt for 1 d. The solvent was removed under reduced pressure and the crude was purified by flash column chromatography on silica gel (EtOAc/n-pentane 30:70) to afford the Ugi adduct 1a as a white solid in 92 % yield (816 mg, 1.8 mmol).

The resulting mixture was stirred at rt for 1 h under an inert atmosphere. After completion of the reaction, HCl (1 mL, 18% solution in water) was added and the mixture diluted with ethyl acetate and washed with water. The organic layer was dried with MgSO4 and the solvent was removed under reduced pressure. The crude residue was purified by flash chromatography on silica gel (Et2O/n-pentane 60:40) to afford isoindolone 2a as a yellow oil in 60% yield (82 mg, 0.24 mmol). Rf 0.22 (Et2O/n-pentane 60:40).
