  Synthesis of 3‐O‐β‐D‐Glucopyranosyl‐(3R)‐hydroxybutanolide (Kinsenoside) and 3‐O‐β‐D‐Glucopyranosyl‐(3S)‐hydroxybutanolide (Goodyeroside A)

  摘要：

  The first synthesis of 3-O-beta-D-glucopyranosyl-(3R)-hydroxybutanolide (Kinsenoside) and 3-O-beta-D-glucopyranosyl-(3S)-hydroxybutanolide (Goodyeroside A) is described. The diastereomers of the aglycon in 2-O-beta-D-gulucopyranosyl-1,2,4-butanetriol derivatives, which were separable precursors of Kinsenoside and Goodyeroside A, were synthesized from optically nonactive 1,2,4-butanetriol and alpha-D-glucopyranosyl trichloroacetimidate in excellent yields.
