A novel protecting group directed diversity leading to the synthesis of bridged bicyclic and six-membered iminocyclitols from a common carbohydrate derived diamino triol under Mitsunobu conditions is reported. When the intramolecular cyclization of benzoyl derivative 16 was carried out under Mitsunobu conditions, an unprecedented one-pot domino intramolecular “cyclization–N → O benzoyl migration–cyclization”
