実験手順

S-Trityl-2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranose (21.0 g.) was suspended in 90 ml. of methanol, cooled to -15° C. and a solution of sodium methoxide prepared from 0.21 g. of sodium and 75 ml. of methanol was added. The mixture was stirred for one hour at room temperature, then concentrated under reduced pressure to give a solid residue. The residue was triturated with water, then chloroform was added. The mixture was filtered and concentrated to give a solid residue which was dried by azeotropic distillation in benzene. Further evaporation of solvent and drying in vacuo gave S-trityl-1-thio-β-D-glucopyranose.
