[摘要]：A series of naturally occurring pyrrolidine alkaloids and analogs, with the general structure of trideoxy-2,5-iminohexitols (imino- or azasugars), have been enantiosynthesized using triorthogonally protected pyrrolidines, previously prepd. from com. D-fructose, as homochiral starting materials. The inhibitory activity of some of the described compds. against glycosidases and glycosyltransferases makes them potential therapeutic agents.
