Procedure

Preparation of (3R,3aR,6S,6aS)-Benzyl 3-hydroxy-6-(tosyloxy)tetrahydro-2H-furo[3,2-b]pyrrole-4(5H)-carboxylate (34). Ethanol (6 mL) was added dropwise to a mixture of 10% palladium on charcoal (50 mg) and anti-(33) (547 mg, 1.26 mmol) under an atmosphere of argon. The argon was replaced by hydrogen then the suspension was stirred at 20° C. for 3.75 hours before filtering the mixture through celite in vacuo. The filter cake was washed with ethanol (40 mL) then the solvents removed in vacuo from the filtrate to obtain (3R,3aR,6S,6aS)-3-hydroxyhexahydro-2H-furo[3,2-b]pyrrol-6-yl 4-methylbenzenesulfonate which was used without further purification.
