[(3R,3aS,6aR)-Hydroxyhexahydrofuro[2,3-β]furanyl Succinimidyl Carbonate Usage And Synthesis

Chemical Properties

Pale-Yellow Solid

Uses

Darunavir intermediate.

Synthesis

1. 26.3 g of tert-butyl methyl ether, 35.09 g (135 mmol) of N,N'-disuccinimidyl carbonate, and 20.00 g (73.0% content) of (3R,3aS,6aR)-hexahydrofuro[2,3-B]furan-3-ol were mixed at room temperature, and the mixture was heated to 40 °C. 2. 11.89 g (150 mmol) of pyridine was added slowly and dropwise to the reaction mixture at 40 °C. 3. the reaction mixture was stirred at 40 °C for 22 hours. 4. Upon completion of the reaction, the reaction solution was cooled to 20 °C and 73.0 g of 2-propanol was slowly added dropwise at 20 °C to precipitate the target product 2,5-dioxopyrrolidin-1-yl ((3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-yl) carbonate. 5. The mixture was further cooled to 0-5°C and stirred at that temperature for 19 hours. 6. The precipitated target product was collected by filtration and washed with an appropriate solvent to give 27.83 g of product (97.8% content, 90% yield, enantiomeric excess >99.9% ee). 7. for the isolation of diastereoisomers, 30.0 g of tert-butyl methyl ether, 11.87 g of (3R,3aS,6aR)-hexahydrofuro[2,3-B]furan-3-ol containing 84.3% of the diastereoisomers, and the enzyme (CHIRAZYME L-2c, -flyo, Roche Diagnostics) were mixed at 25°C. 8. 3.31 g (38.4 mmol) of ethyl acetate was added dropwise to the mixture and the insoluble material was removed by filtration after stirring at 25 °C for 40 hours. 9. The filtrate was concentrated to give 12.73 g of a mixture containing (3R,3aS,6aR)-hexahydrofuro[2,3-B]furan-3-ol and its 3S,3aS,6aR isomer (90% yield, diastereoisomer ratio 100.0/0.0).
