Solvent-free, instant, ambient, n-boc protection of amines -A green, recyclable
heterogenous acid catalysis by Amberlite-IR 120
Author(s): Vijay Kumar Pasala
A facile and versatile method for the N-tert-butoxycarbonylation of amines with Boc2O in the presence Amberlite-IR 120 under solvent-free conditions. This method is general for the preparation of N-Boc derivatives of both aliphatic (cyclic and acyclic) and aromatic amines.
