A flexible route towards five-membered ring imino sugars starting from a chiral α,β-epoxy aldehyde has been developed. The approach relies on the use of the versatile epoxyamine intermediate 4, from which regiocontrolled epoxide opening affords diastereoselective access to trisubstituted pyrrolidines. Described here is the nucleophilic attack at C-2 of the pivotal epoxypyrrolidine 10, leading to the

The mycobacterialcellwall is a promising target for the development of new antituberculosis drugs. We report the synthesis and preliminary biological evaluation of imino sugar−oligoarabinofuranoside hybrids, a new class of mycobacterial arabinosyltransferase inhibitors. These hybrids were built from various chiral polyhydroxylated pyrrolidines (imino sugars) linked to small oligoarabinofuranosides
