  A versatile chiral compound, (1R,6R,8R,9R)-8,9-isopropylidenedioxy-7-oxabicyclo[4.3.0]non-4-en-3-one (6), was efficiently synthesized from d-glucose. The synthesis featured an intramolecular aldol cyclization of 3-C-acetylmethyl-3-deoxy-1,2-O-isopropylidene-α-d-ribo-pentodialdo-1,4-furanose, which was readily derivatized from the known Wittig adducts of 1,2:5,6-di-O-isopropylidene-α-d-ribo-hexofuranos-3-ulose. The utility of this highly functionalized chiral synthon 6 was embodied by conversion to four optically active pseudosugars, these are pentaacetyl derivatives of pseudo-α-l-altropyranose, pseudo-β-d-glucopyranose, pseudo-2-amino-2-deoxy-β-l-altropyranose, and pseudo-2-amino-2-deoxy-α-d-glucopyranose (a derivative of pseudoglucosamine). The transformation of 6 to the pseudo sugars involved 1) a stereospecific epoxidation of the double bond in 6 providing (1R,4S,5S,6S,8R,9R)-4,5-epoxy-8,9-isopropylidenedioxy-7-oxabicyclo[4.3.0]nonan-3-one (8), and 2) an exclusive diaxial ring opening of the β-epoxy alcohols, which were derived from 8, providing (1R,3R,4S,5S,6S,8R,9R)-8,9-isopropylidenedioxy-7-oxabicyclo[4.3.0]nonane-3,4,5-triol (11) or (1R,3S,4S,5R,6S,8R,9R)-4-azido-8,9-isopropylidenedioxy-7-oxabicyclo[4.3.0]nonane-3,5-diol. Treatment of (1R,2S,3S,4S,5R)-3,4,5-tris(benzyloxy)-2-hydroxycyclohexanecarbaldehyde, which was derived from 11, with methanesulfonyl chloride, and successive sodium borohydride reduction provided (3S,4S,5R)-3,4,5-tris(benzyloxy)-1-cyclohexene-1-methanol (19). Hydroboration of 19 proceeded from the less hindered side stereoselectively.
