SYNTHESIS OF SWEET TASTING PSEUDO-β-FRUCTOPYRANOSE

Abstract Pseudo-β-Dl-fructopyranose has been synthesized from Dl-1,2-di-O-acetyl-(1,3/2)-3-bromomethyl-5-cyclohexene-1,2-diol by two reaction routes. The pseudosugar was found to be sweet and this fact provides a strong support for Shallenberger’s sweetness-structure hypothesis.
