Related Products of 6971-74-0, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 6971-74-0 as follows.

General procedure: N-Benzoylsulfonamide 1a (27.5 mg, 0.1 mmol), [RhCl2Cp*]2 (1.2 mg, 0.002 mmol), and Cu(OAc)2¡¤H2O (40.0 mg, 0.20 mmol) were loaded in a dry vial, which was subjected to evacuation/flushing with dry argon three times. Anhydrous toluene (1.0 mL) solution of tert-butyl acrylate 2a (17.4 muL, 0.12 mmol) was syringed into the mixture, which was then stirred at 130 C for 24 h or until the starting material had been consumed as determined by TLC. Upon cooling to room temperature, all volatiles were evaporated and the residue was purified by preparative TLC (ethyl acetate/hexane 1:2) to give isoindolinone 3a in 88% yield
