A Highly Stereoselective Construction of 1,2-trans-β-Glycosidic Linkages Capitalizing on 2-Azido-2-deoxy-D-glycosyl Diphenyl Phosphates as Glycosyl Donors.
11- 196 —
The phosphates (Ia), (Ic), (IIa), (IIc), (III), and (IV) are found to be efficient glycosyl
donors. They allow formation of disaccharides in high yields and with high levels of
β-selectivity. In contrast, starting from the acetyl analogues [cf. (Ib) and (IIb)] only
small amounts of desired disaccharides are obtained. — (TSUDA, T.; NAKAMURA,
