The reaction of compound 6 with N -bromosuccinimide afforded methyl 4- O -benzoyl-6-bromo-2,6-dideoxy-3- C -methyl-3- O -methyl-α- D - xylo -hexopyranoside (7) in high yield. Compound 7 was converted, by catalytic debenzoylation and reductive debromination, into methyl α- D -arcanoside (9). Acid-catalyzed hydrolysis of glycoside 9 gave D -arcanose ( 10 ).
