A Siloxane-Bridged Glycosyl Donor Enables Highly Stereoselective β‑Xylulofuranosylation

糖类合成

立体选择性糖基化

We report a siloxane-protected donor (7) for the highly stereoselective formation of β-(2,3-cis)-xylulofuranosyl bonds. Glycosylation reactions with 7 gave >80% yields, and only β-xylulofuranosides we

Stereoselective Synthesis of Allyl- C -mannosyl Compounds: Use of a Temporary Silicon Connection in Intramolecular Allylation Strategies with Allylsilanes

糖类合成

立体选择性C-糖基化

Methyl mannoside 16 containing an allyldimethylsilyl ether at C(2) was synthesized in nine steps from d-mannose. Reaction with TMSOTf in MeCN at room-temperature effected C-glycosylation to provide th

Synthesis and Structural Analysis of the Anilides of Glucuronic Acid and Orientation of the Groups on the Carbohydrate Scaffolding

糖类合成

药物分子结构

The synthesis of anilides derived from glucuronic acid is described. Secondary anilides had a Z configuration in the solid state and showed intramolecular and intermolecular hydrogen bonding. However,
