The enantioselective synthesis of (–)-allosamizoline (2a), the aminocyclitol moiety of allosamidin (1a), was achieved by starting from D-glucosamine (3). Intramolecular nitrile oxide cycloaddition was adopted as the key step to construct a function

Coupling reactions between 1-chloro-2,3-dideoxyribose and silylated pyrimidines have been examined from the point of stereoselectivity. When the reaction was carried out in chloroform, the selectivity was in the anomeric ratio of α:β=4:6. On the ot
