摘要

The protection of amines with tert-butyloxycarbonyl (Boc) group is a widely used reaction in organic synthesis because of its inertness toward catalytic hydrogenolysis and resistance toward hydrolysis under most basic conditions and nucleophilic reagents. 1 N-Boc deprotection is generally achieved under mild acidic conditions 1 such as trifluoroacetic acid (TFA), either neat or in combination with CH 2 Cl 2, HCl in EtOAc, H 2 SO 4 in tBuOAc, pTSA, methanesulfonic acid in ...
