Selective Deprotection Method of N-Phenylcarbamoyl Group
摘要:
We report an improved method for the selective deprotection of the N-phenylcarbamoyl group, which yields the corresponding alcohol without affecting other protecting groups. Deprotection was performed using di-tert-butyl dicarbonate and tetra-n-butylammonium nitrite (Boc(2)O and Bu4NNO2) in pyridine at room temperature. This method is also effective for deprotecting the fluorous N-phenylcarbamoyl group.
