Cleavage of carbamates

Recent Literature

A general, mild, and efficient reductive cleavage of aryl O-carbamates to phenols using the Schwartz reagent is selective and tolerates a large number of functional groups. The cleavage may be carried out by direct or by an economical in situ procedure; and, notably, establishes a synthetic connection to the directed ortho metalation strategy.

An improved method for the selective deprotection of N-arylcarbamoyl groups yields the corresponding alcohols without affecting other protecting groups. Deprotection was performed using di-tert-butyl dicarbonate and tetra-n-butylammonium nitrite (Boc2O and Bu4NNO2) in pyridine at room temperature.
