ß-D-Arabinosyl 1-C-sulfonic acid.

ABSTRACT

A short synthetic route to ß,d-arabinofuranosyl 1-C-sulfonic acid (7), a possible biomimetic for the arabinofuranosyl anomeric phosphate, is described. The furanosyl 1-C-sulfonate was prepared by buffered DMDO oxidation of an S-acetyl-1-thio-ß-arabinofuranose derivative. Deprotection under mild conditions allowed isolation of the free sulfonic acid without desulfonylation.
