Acidic Solvent-free Removal of Amine-protecting Diphenylmethyl Groups in the Presence of Camphorsulfonic Acid
We developed novel reaction conditions for the removal of the diphenylmethyl group, which is one of the most important protecting groups for amines. The reaction was promoted by adding one equivalent of camphorsulfonic acid in aqueous media, and no acidic solvent was required.
