Titanocene(III) chloride (Cp2TiCl) mediated radical induced allylation of aldimines for the preparation of homoallyl amines is described. The radical was generated from the allylbromide using Cp2TiCl as the radical source. Formal synthesis of C(4)–C(5′)-linked 4′-deoxy aza-disaccharide is demonstrated and a study toward the bicyclic skeleton of alkaloids was also accomplished. The radical initiator
