A latent/active glycosylation strategy is efficient for rapid ­assembly of oligosaccharides. We recently developed novel OPTB/OPSB and SPTB/SPSB glycosides as two pairs of latent/active glycosyl donors. The active OPSB and SPSB glycosyl donors are efficiently activated by Tf2O via an interrupted Pummerer reaction mechanism. In this account, the design, developments, mechanism studies and applications of these new glycosylation methodologies are described. 1 Introduction 2 Conceiving Ideas 3 Synthesis of OPSB and SPSB Glycosides 4 Substrate Scope 5 Application in the Synthesis of Natural Products 6 Conclusion

潜伏/活性糖基化中的普默勒反应中断

潜在/活性糖基化策略对于寡糖的快速组装是有效的。我们最近开发了新型 OPTB/OPSB 和 SPTB/SPSB 糖苷作为两对潜在/活性糖基供体。活性 O​​PSB 和 SPSB 糖基供体被 Tf2O 通过间断的 Pummerer 反应机制有效激活。在这个帐户中，描述了这些新的糖基化方法的设计、发展、机制研究和应用。1 引言 2 构思 3 OPSB 和 SPSB 糖苷的合成 4 底物范围 5 在天然产物合成中的应用 6 结论
