Reaction Steps

To a mixture of 1.00 g of ethyl cis-2-hydroxy-1-cyclopentane carboxylate, 8.00 mL of chloroform, 16.0 mL of normal hexane, and 1.77 mL of 3,4-dichlorobenzyl-2,2,2-trichloroacetimidate was added 0.335 mL of trifluoromethane sulfonic acid at room temperature under a nitrogen atmosphere, followed by stirring for 3 hours. The insoluble materials were removed by filtration, and to the filtrate was added a saturated aqueous sodium hydrogen carbonate solution under ice-cooling to adjust the pH to about 7, followed by extraction with chloroform. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was evaporated. The obtained residue was purified by silica gel column chromatography (normal hexane/ethyl acetate) to obtain 1.27 g of ethyl cis-2-benzyloxy-1-cyclopentane carboxylate as a colorless oily substance.
