摘要

Fluorination reactions of 2-O-benzyl-6-deoxy-1, 2-O-isopropylidene-α-D-gluco-, β-L-ido-, α- D-allo-, and β-L-talo-furanoses (1, 2, 3, and 4) were investigated. The reaction of 1 with diethylaminosulfur trifluoride (DAST) predominantly produced 2-O-benzyl-5, 6-dideoxy-5- fluoro-1, 2-O-isopropylidene-α-D-glucofuranose with the retention of the configuration at C- 5. Both of the fluorides with retained and inverted configurations were obtained in the ...
