실험 절차

Preparation of (3R,3aR,6R,6aS)— Benzyl 3-hydroxy-6-(tosyloxy)tetrahydro-2H-furo[3,2-b]pyrrole-4(5H)-carboxylate (34b). Ethanol (1.5 mL) was added dropwise to a mixture of 10% palladium on charcoal (10 mg) and anti-(33b) (12.0 mg, 0.028 mmol) under an atmosphere of argon. The argon was replaced by hydrogen then the suspension was stirred for 1.75 hours before filtering the mixture through celite in vacuo. The filter cake was washed with ethanol (7.5 mL) then the solvents removed in vacuo from the filtrate. The residue was azeotroped with toluene (2 mL) to obtain (3R,3aR,6R,6aS)-3-hydroxyhexahydro-2H-furo[3,2-b]pyrrol-6-yl 4-methylbenzenesulfonate (7.6 mg, 89%) as a pale yellow oil which was used without further purification. TLC (Rf=0.01, EtOAc:heptane 1:1), HPLC-MS 300.1 [M+H]+, 621.2 [2M+Na]+.
