The Cglycosyl analog of an N-linked glycoamino acid
摘要:
The synthesis of a new glycoamino acid derivative, a direct C-analog of N-4-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-L-Asn is described. The C-glycoside is prepared by a tandem Horner-Emmons-Wadsworth olefination-Michael addition between an aspartyl beta-keto phosphonate and a 4,6-O-benzylidene GlcNAc sugar.
