  Comparison of the Armed/Disarmed Building Blocks of the d-Gluco and d-Glucosamino Series in the Context of Chemoselective Oligosaccharide Synthesis

  摘要：

  A very elegant Fraser-Reid armed-disarmed approach recently expanded to the building blocks of the superarmed and superdisarmed series shows very high utility in chemoselective oligosaccharide synthesis. Although a number of studies dedicated to the chemoselective activation of 2-amino-2-deoxysugars have emerged, little remains known about how the reactivity of the armed/disarmed building blocks of the neutral sugars directly compares to that of their 2-aminosugar counterparts. A preliminary study of this comparative reactivity is presented.

• Thioglycosides Protected as Trans-2,3-Cyclic Carbonates in Chemoselective Glycosylations
  作者：Tong Zhu、Geert-Jan Boons

  DOI：10.1021/ol016869j

  日期：2001.12.1

  [GRAPHICS]Thioglycosides protected as trans-2,3-cyclic carbonates have significantly lower anomeric reactivities than fully acylated and N-acyl-protected thioglycosides and can be used as acceptors in chemoselective glycosylations with a wide range of thioglycosyl donors. The resulting thioglycosides can be further activated to give 1,2-cis-linked glycosides.
