Chiron approach strategy to the bicyclic oxazolidinylpiperidine: a building block for preparing mono- and bi-cyclic iminosugars

A chiron approach to the synthesis of bicyclic oxazolidinylpiperidine, a synthetically potential building block for preparing mono- and bi-cyclic iminosugars, is reported from d-glucose using ring closing metathesis as the key step.
