An efficient approach to hydroxylated pyrrolidine and piperidinederivatives through the intramolecular hydroamination catalyzed by a Cu(I)-Xantphos system is described. The transformation allows for the short synthesis of N-alkylated aza-sugars without a protection-deprotection event of the hydroxy groups.
