Abstract

Functional group manipulation through the protection–deprotection strategy is an unavoidable exercise in the synthesis of multifunctional target molecules. In this context protection of phenols, thiols, amines and alcohols becomes a frequently desired transformation due to the prevalence of these functionalities in drugs and pharmaceuticals. Protection of these functionalities is usually achieved through acylation with anhydrides 1., and due to their ease of ...
