Synthesis of 3-O-β-D-Glucopyranosyl-(3R)-hydroxybutanolide (Kinsenoside) and
(Goodyeroside A). — The
28- 198 3-O-β-D-Glucopyranosyl-(3S)-hydroxybutanolide
large-scale synthesis of Kinsenoside and Goodyeroside A (XII) is based on the glycosylation of the partly protected, optically nonactive butanetriol (V) according to the
imidate method. Goodyeroside A (XII), a diastereomer of Kinsenoside on the aglycon
part, and its isomer are synthesized using the same route with construction of the aglycon residue after the regio- and stereoselective glycosylation. The structure of (XII) is
newly confirmed by a comparison with the spectral data of its perbenzoate. —
