摘要: The development of glycobiology relies on the sources particular oligosaccharides in their purest forms. As isolation oligosaccharide structures from natural is not a reliable option for providing samples with homogeneity, chemical means become pertinent. growing demand diverse has prompted advancement strategies to stitch sugar molecules precise stereo- and regioselectivity through formation glycosidic bonds. This Review will focus key developments towards O-glycosylations current century. Synthesis novel glycosyl donors acceptors unique activation successful glycosylation are discussed. concludes summary recent comments future prospects.
