Synthesis of (R)-8-hydroxy-2,7-dimethyl-(4E,6E)-octadienyl beta-D-glucopyranoside (1), a glycosidic precursor of marmelo oxides, the volatile components of quince fruit, Cydonia oblonga Mill., was achieved starting from (S)-3-hydroxy-2-methylpropanoate (5). The conjugated diene moiety was constructed in one step by a Horner reaction, and the final glycosidation was executed via the chloroimidate method.
