反応手順
Two grams of 5-O-(tert-butyldiphenylsilyl)-2,3-dideoxy-4-thioribofuranose (prepared according to J. A. Secrist et al., J. Med. Chem., 1992,35,533) is stirred with 0.456 g of thioacetic acid in 25 ml of methylene chloride and 0.0.025 g of toluenesulfonic acid for 68 hours. On workup the reactiion is adsorbed onto magnesium silicate and then flash chromatographed on silica gel to give 1.5 g of the desired product.
