  Ferrier Glycosylation Reaction Catalyzed by Bi(OTf)3-Montmorillonite K-10: Efficient Synthesis of 3,4-Unsaturated Sialic Acid Derivatives: Synthesis and Biological Evaluation as Inhibitors of Human Parainfluenza Virus Type 1

  摘要：

  The reaction of the 4,5-oxazoline derivative of sialic acid with various alcohols was effectively promoted by a catalytic amount of montmorillonite K-10 clay-supported Bi(OTf)(3) to produce a variety of 3,4-unsaturated sialic acids via the Ferrier glycosylation reaction in moderate yields. The deprotection of the isopropylidene group and hydrolysis of the ester group of 7a-g gave 4a-f, whose inhibitory activities against hPIV-1 sialidase were studied.
