- Synthesis of pyrrolidine iminosugars has been described from d-glycals via dihydroxylation, oxidative cleavage and double nucleophilic displacement as the key steps. The pyrrolidines obtained have been utilized for the synthesis of important bicyclic iminosugars, viz. (−)-lentiginosine and (−)-swainsonine and their 8a-epimers, which are known to be glycosidase inhibitors.
