β-D-Arabinosyl 1-C-sulfonic acid ^*

Abstract

A short synthetic route to β, 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-β-arabinofuranose derivative. Deprotection under mild conditions allowed isolation of the free sulfonic acid without desulfonylation.
