摘要：

A ring-closing metathesis approach was employed for the synthesis of a beta-C-glycoside analog of the immunostimulant KRN7000. The protected Gglycosyl amino acid derivative 18 was converted to amino-olefin 20, and osmylation served to install the diol unit as a mixture of separable syn and anti isomers. Deprotection to the hydroxy-amine 21 was followed by N-acylation and debenzylation to deliver the target compound 5. (C) 2004 Elsevier Ltd. All rights reserved.
