N-Substituted derivatives of 1,4-dideoxy-1,4-imino-D-mannitol (DIM), the pyrrolidine core of swainsonine, have been synthesized efficiently and stereoselectively from D-mannose with 2,3:5,6-di-O-isopropylidene DIM (10) as a key intermediate. These N-substituted derivatives include N-alkylated, N-alkenylated, N-hydroxyalkylated and N-aralkylated DIMs with the carbon number of the alkyl chain ranging
swainsonine的吡咯烷核心1,4-二脱氧-1,4-亚氨基-D-甘露醇(DIM)的N-取代衍生物已由D-甘露糖与2,3:5,6-di高效立体合成- ö异亚丙基DIM(10),为关键中间体。这些Ñ取代衍生物包括Ñ烷基化,Ñ -alkenylated,Ñ -hydroxyalkylated和Ñ -aralkylated的DIM与烷基链从一到九的碳原子数。获得33 N针对各种糖苷酶对取代的DIM衍生物进行了分析,从而可以系统评估其糖苷酶抑制谱。尽管DIM的N-取代降低了其对α-甘露糖苷酶的抑制活性,但是一些衍生物显示出对其他糖苷酶的显着抑制作用。
