ester that on ester reduction, epoxidation, regioselective oxirane opening by sodium azide and hydrogenation led to sugar amino alcohols--immediate precursors for 1-deoxy-homonojirimycin 3a,b, and polyhydroxylated homoazepanes 4a,b. Our synthetic approach and glycosidase inhibitory activity is reported.
D-葡萄糖和L-ido衍生的烯丙基原酸酯的Johnson-Claisen重排提供了γ,δ-不饱和酯,该酯经酯还原,环氧化,叠氮化钠的区域选择性环氧乙烷开环和加氢反应生成糖氨基醇-为1的直接前体-脱氧-homonojirimycin 3a,b,和多羟基化高氮epa酮4a,b。报告了我们的合成方法和糖苷酶抑制活性。
