Synthesis of 1,4-dideoxy-1,4-imino-D-mannitol

摘要

Swainsonine and analogs, namely, 1,4-­dideoxy-1,4-imino-D-mannitol and the novel ring contracted swainsonines, (1S,2R,7R,7aR)-1,2-trihydroxypyrrolizidine and (1SD,2R,7S,7aR)-1,2,-7-trihydroxypyrrolizidine, are synthesized from the divergent intermediate, 4,5-­anhydro-1-azido-1-deoxy-2,3-O-isopropylidene-D-­talitol. These novel compounds are glycosidase inhibitors.
