Jacobsen and Pedersen153 confirmed the generation of benzoxonium ion 126 by treatment of compound 125 with triphenylmethyl fluoroborate in acetonitrile, but they treated it with tetraethylammonium bromide, obtaining a 3 2 mixture of the a and /3 anomers of methyl 2,5-di-0-benzoyl-3-bromo-3-deoxy-D-xylofuranoside (134) in a yield of 74%. This mixture could be anomerized to give the pure )8 anomer (overall yield 60%) by treatment with hydrogen bromide followed by the action of methanol. [Pg.109]

The reaction of methyl 2,3-anhydro-j3-D-ribofuranoside with hydrogen bromide in acetic acid-acetic anhydride led to the formation of methyl 2,3-di-0-acetyl-5-bromo-5-deoxy-ajS-D-xylofuranoside, presumably via the intermediacy of the 3,5-acetoxonium ion. Similar treatment of methyl 2,3-anhydro-5-0-benzoyl-)8-D-ribofuranoside furnished methyl 2-0-acetyl-3-0-benzoyl-5-bromo-5-deoxy-ajS-D-xylofuranosides. [Pg.58]
