General Description
(3aS,4S,6aR)-4-Methoxytetrahydrofuro[3,4-b]furan-2(3H)-one is a chiral bicyclic lactone containing a fused tetrahydrofuro-furan ring system. This compound is an advanced building block for asymmetric synthesis, providing a rigid, oxygen-rich heterocyclic scaffold with defined stereochemistry and multiple functionalization sites.
Application
Used mainly as a high purity intermediate, (3aS,4S,6aR)-4-Methoxytetrahydrofuro[3,4-b]furan-2(3H)-one finds application in the synthesis of complex pharmaceutical agents, particularly in the production of protease inhibitors and antiviral drugs.
Quaedflieg P J L M et al. developed two short and efficient synthetic routes to bis-THF-alcohol 2, a key intermediate for the investigational HIV protease inhibitor TMC114 (1). Both routes commence from S-2,3-O-isopropylideneglyceraldehyde (4) as the chiral source. The synthetic sequence involves a diastereoselective Michael addition of nitromethane, which predominantly yields the syn isomers 6. These are then subjected to Nef oxidation and cyclization to afford lactone acetals 8, followed by a reduction and final cyclization to deliver the target molecule 2.
