Gold(I)-Catalyzed Intermolecular Rearrangement Reaction of Glycosyl Alkynoic β-Ketoesters for the Synthesis of 4- O-Glycosylated 2-Pyrones

A new gold(I)-catalyzed rearrangement reaction with glycosyl alkynoic β-ketoesters as substrates is developed. The rearrangement reactions under the catalysis of PPh3AuOTf proceeded smoothly to afford a range of 4-O-glycosylated 2-pyrones. Base

Gold(I)-Catalyzed Glycosylation with Glycosyl Ynenoates as Donors

A simple and versatile glycosylation method with both armed and disarmed glycosyl ynenoates as donors is developed. Employing a gold(I) complex as catalyst with or without the assistance of TfOH, the scope of the present glycosylation protocol is very wid

Synthesis of a chlorogenin glycoside library using an orthogonal protecting group strategy

Naturally occurring spirostanol saponins bear a chacotriose, α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→4)] -β-d-glucopyranose residue as the oligosaccharide moiety which is believed to be important for biological activity. Herein the development of a concise, combinatorial method for the synthesis of two series of glycan variants at the 2′ and/or 4′ positions of chacotriose is described and the structure-activity relationships of the glycone part at 3-OH of chlorogenin investigated. These compounds were found to be weakly-cytotoxic toward leukemia cell lines CCRF and HL-20, indicating that the chacotriose moiety is important for anticancer activity.
