A mild and efficient chemoselective protection of amines as N-benzyloxycarbonyl derivatives in the presence of La(NO3)3·6H2O under solvent-free conditions
摘要:
A facile and versatile method for the chemoselective N-benzyloxycarbonylation of amines has been developed by treatment with benzyloxycarbonyl chloride (Cbz-Cl) in the presence of lanthanum(III) nitrate hexahydrate under solvent-free conditions. The method is general for the preparation of N-Cbz derivatives of aliphatic (acyclic and cyclic) and aromatic amines. (c) 2006 Elsevier Ltd. All rights reserved.
