Stereospecific Synthesis of Spirohydantoins of β-Glucopyranose: Inhibitors of Glycogen Phosphorylase.
-The key intermediate in the synthesis of title compounds (VIII), the bicyclic lactone (V), is readily prepared from azidolactone (I) (or its α-azido isomer). The rigid structure of (V) guarantees the . beta.-configuration of the nitrogen function after ring opening of the lactone by attack of ammonia, amines, hydrazine, or hydroxylamine. -(KRUELLE, T. M.;
