enzymatically hydrolyzed. The design and synthesis of novel C-linked glycans should provide catabolically stable glycoproteins useful for understanding and regulating important biological processes. Our efforts are currently directed toward the synthesis of C-glycosides of ulosonic acids. This paper describes the first synthesis of a serine-based neuraminicacid C-glycoside. The protecting group chemistry

The synthesis of a new series of D-erythro-homoceramide analogues is described. Several synthetic approaches were investigated. Homoceramides can be successfully synthesized from L-homoserine as chiral buildingblock and a protected Weinreb-amide as a key intermediate. The synthesis of short-chain analogues with a heptyl side chain, as well as with a phenyl residue in the sphingoid part (instead of
