62% | General procedure: To a solution of 11 (40.1g, 170mmol) in THF (150mL), a solution of i-PrMgBr (0.78M in THF, 229mL, 179mmol) was added dropwise at-40C and stirred at the same temperature for 1.5h. Next, a solution of 1-tert-butoxylcarbonyl-2-pyrrolidinone (31.6g, 170mmol) in THF (180mL) was added dropwise at-40C. After stirring at the same temperature for 1.5h and then stirring at room temperature for 1h, the reaction was quenched with saturated aqueous NH4Cl. The reaction mixture was extracted with AcOEt, and organic layer was washed with water and brine and dried over Na2SO4. After filtration, the solvent was concentrated under reduced pressure and the residue was recrystallized with AcOEt/n-hexane to give 29.5g (51%) of 22a as a pale-yellow solid: |
