1-Benzyl-3-pyrrolidinone is a substrate used to prepare chiral, alkenyl sulfoximines leading to highly functionalized diazabicycles. | [Uses]
Substrate used to prepare chiral, alkenyl sulfoximines leading to highly functionalized diazabicycles.1 | [General Description]
The equilibrium constant for the ketoreductase-catalyzed reduction reaction of 1-benzyl-3-pyrrolidinone has been measured in n-hexane. 1-Benzyl-3-pyrrolidinone on enzymatic asymmetric reduction yields enantiopure 1-benzyl-3-hydroxypyrrolidine, well known intermediate for various drugs. | [Synthesis]
General procedure for the synthesis of 1-benzyl-3-pyrrolidinone from N-benzyl-3-hydroxypyrrolidine: 12.50 g of oxalyl chloride was slowly added dropwise to 70 mL of dichloromethane, stirred and cooled to -65 °C or lower. Subsequently, a dichloromethane solution of 5.0 g of DMSO was added dropwise, keeping the reaction temperature at -65°C. After dropwise addition, stirring was continued for 30 minutes. Next, 8.80 g of a dichloromethane solution of 1-benzyl-3-hydroxypyrrolidine was added dropwise, maintaining the temperature at -65 °C, and the reaction progress was monitored by TLC. After 2 hours of reaction, triethylamine was slowly added dropwise at -65 °C, controlling the temperature at -65 °C, and stirring was continued for 30 minutes after completion of the dropwise addition. Subsequently, the temperature of the reaction system was raised to 0 °C and water was added dropwise to transform the suspension into a clarified solution. The organic layer was separated, washed with brine and dried to give 8.00 g of 1-benzyl-3-pyrrolidone in 90.90% yield and 95% HPLC purity. | [References]
