A facile one-pot two-enzyme chemoenzymatic approach has been established for 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 preparative scale. Used as an effective probe, Neu4,5Ac2α3GalβpNP was found to be a suitable substrate by human influenza A viruses but not bacterial sialidases. One-pot multienzyme (OPME) synthesis: Monotreme milk oligosaccharides and other sialosides containing a 4-O-acetyl-sialic acid were synthesized in gram (1.33 g for Neu4,5Ac2α3Lac) or preparative (10–56 mg) scales using a one-pot two-enzyme (OP2E) sialylation system containing a bacterial cytidine 5′-monophosphate (CMP)-sialic acid synthetase and Pasteurella multocida sialyltransferase 3 (PmST3).
