antigens are a family of widely distributed histo-blood group antigens sharing the Siaα2,3(GalNAcβ1,4)Gal trisaccharide determinant. Despite their significant biological importance, the synthesis of these complex carbohydrate antigens is challenging. Herein, we report a highly efficient and green synthesis of diverse Sda antigens with different underlying structures and sialic acid forms utilizing 6 multienzyme

Effective one-pot multienzyme (OPME) synthesis of monotreme milk oligosaccharides and other sialosides containing 4-O-acetyl sialic acid
A facile one-pot two-enzyme chemoenzymatic approach has been established for the gram (Neu4,5Ac2α3Lac, 1.33 g) and preparative scale (Neu4,5Ac2α3LNnT) synthesis of monotreme milk oligosaccharides. Other O-acetyl-5-N-acetylneuraminic acid (Neu4,5Ac2)- or 4-O-acetyl-5-N-glycolylneuraminic acid (Neu4Ac5Gc) -containing α2-3-sialosides have also been synthesized in the preparative scale. Used as an effective
Chemoenzymatic Synthesis of Sialosides Containing 7-<i>N</i>- or 7,9-Di-<i>N</i>-acetyl Sialic Acid as Stable <i>O</i>-Acetyl Analogues for Probing Sialic Acid-Binding Proteins
(OPME) sialylation systems for highly efficient synthesis of sialosides containing multiple azido groups. Conversion of the azido groups to N-acetyl groups generated the desired sialosides. The hydrophobic and UV-detectable benzyloxycarbonyl (Cbz) group introduced in the synthetic acceptors of sialyltransferases was used as a removable protecting group for the propylamine aglycon of the target sialosides
