A concise synthesis of unnatural (+)-5-epi-nojirimycin-δ-lactam via asymmetric reduction of a meso-imide

Nojirimycin-δ-lactam skeleton was synthesized by asymmetric reduction of a cyclic triacetyloxy meso imide with a chiral β-amino thiol ligand. The resulting product was converted to unnatural (+)-5-epi-nojirimycin-δ- lactam.
