Highly Diastereoselective Synthesis of Anomeric ฮฒ-O-Glycopyranosyl Carbamates from Isocyanates. -Isocyanates (II) react with anomerically unprotected glycopyranosides ( cf. (I)) to yield the corresponding urethanes with high ฮฒ-selectivity. The method can also be applied to isocyanates, generated in
