| Abstract: | In chemical glycosylation reactions, a glycosyl donor couples with a glycosyl acceptor through glycosidic linkage. Most of the products end up with a mixture due to the formation of a stereogenic center at the anomeric carbon. Activation with a suitable Lewis acid and introduction of the non‐participating protecting group on donor and acceptor results in a selective product. Herein, we used a suitably protected donor and acceptor which produced an orthogonally protected building block with α‐selectivity. We used also a donor for the synthesis of modified phosphoribosylated amino acid. The formation of glycoside products can be used to synthesize complex biologically important organic molecules. |
