  ABSTRACT: An efficient and versatile practical protocol for the chemoselective N-tert-butoxycarbonylation of amines using Nano-γ-Fe2O3 and (BOC)2O. Nano-γ-Fe2O3 was applied as an efficient, green, heterogeneous and reusable catalyst at ambient temperature; the method is general for the preparation of N-Boc derivatives of aliphatic, heterocyclic, aromatic as well as amino acid derivatives.
