alpha-Galactosyl ceramide is synthesized fromd-lyxose in 32% overall yield in five steps. The short and efficient protocol involves a one-pot protection and glycosidation of D-lyxose with D-galactosyl iodide as a key step. The alpha-linked disaccharide obtained was subsequently transformed into alpha-galactosyl ceramide in four steps involving Z-selective Wittig olefination at C-1, stereo-inversion
