Popis: | A novel class of chiral crown ether analogues incorporating carbohydrate subunits can be easily prepared from methyl a-D-mannopyranoside. By a short reaction sequence involving either alkylations using a dibutylstannane intermediate or by phase transfer catalyzed etherification well defined disaccharide mimetics were obtained, which are suitable starting materials in Richman-Atkins cyclizations. The combination of several various reaction partners led to structurally interesting ring systems differing in ring size, number of carbon and hetero atoms (20-40) as well as kind of sugar subunits. |
