実験手順

A solution of 2.5 g of toluene-4-sulfonic acid (3R,3aS,6R,6aR)-6-hydroxy-hexahydro-furo[3,2-b]furan-3-yl ester in 30 ml of DMF is heated with 0.8 g of sodium azide under reflux for 2 hours, solvent is distilled off and the distillation residue obtained is dissolved in EtAc and extracted with H2O. The organic phase obtained is dried and solvent is evaporated. (3R,3aR, 6S,6aR)-6-azido-hexahydro-furo[3,2-b]furan-3-ol is obtained.
