  Chemoenzymatic Syntheses of iGb3 and Gb3

  摘要：

  [GRAPHICS]Efficient chemoenzymatic syntheses of iGb3 and Gb3 have been developed. Isoglobotrihexose and globotrihexose were enzymatically synthesized by a three-enzyme system in both solid and solution phases. Then iGb3 and Gb3 were chemically synthesized by coupling of the corresponding trisaccharides with lipid.
