F. Ponten et G. Magnusson, PREPARATION OF 2,3-ANHYDROALLOPYRANOSIDES FUNCTIONALIZED IN THE 6-POSITION, Acta chemica Scandinavica, 48(7), 1994, pp. 566-569
Treatment of methyl 2,3-anhydro-6-bromo-6-deoxy-alpha-D-allopyranoside
with sodium phenylsulfinate, decanethiol, and 2-furylmethanethiol gav
e sugar epoxides carrying sulfone or sulfide functionalities in the 6-
position. Oxidation of the sulfides gave the corresponding sulfones.
