Potassium Carbonate → HCID 57213173, compound

Participants

Reaction Steps

To 100 ml of methanol were added 9.76 g {17.4 mM) of (3R,4R,5R,6R) 4,5-diacetoxy-3,6-dibenzyloxy-1,1,8,8-tetramethoxyoctane [20] obtained via the same route as described above and 6.17 g (43.5 mM) of potassium carbonate. The mixture was heated for 2 hours under reflux while stirring. After it was confirmed by thin layer chromatography that the reaction was completed, the solvent was distilled off under reduced pressure. Water was added to the residue and the mixture was extracted with diethyl ether. After the extract was washed with saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure to give 7.55 g (15.8 mM) of (3R,4R,5R,6R) 3,6-dibenzyloxy-1,1,8,8-tetramethoxyoctane-4,5-diol [21]. Yield, 91%.
