Reaction Steps

(3R,3aR,6S,6aS)-(9H-Fluoren-9-yl)methyl 6-chloro-3-hydroxytetrahydro-2H-furo[3,2-b]pyrrole-4(5H)-carboxylate (70). Ethanol (8.5 mL) was added dropwise to a mixture of 10% palladium on charcoal (55 mg) and alcohol (68) (550 mg, 1.85 mmol) under an atmosphere of argon. The argon was replaced by hydrogen then the suspension was stirred for 1 hour 35 minutes before filtering the mixture through celite in vacuo. The filter cake was washed with ethanol (45 mL) then the solvents removed in vacuo from the filtrate. The residue was azeotroped with toluene (3×5 mL) to obtain (3R,3aR,6S,6aS)-6-chlorohexahydro-2H-furo[3,2-b]pyrrol-3-ol (69) which was used without further purification.
