Concise and selective: The title one‐pot sequence allows formation of the enone functionality and subsequent cross‐coupling. The process provides access to highly functionalized cyclic enolones and enaminones from readily accessible β‐heteroatom‐substituted cyclic ketones.

efficient catalyst for the selective acetylation of alcohols, phenols and amines in the absence of any solvent and also for the chemoselective deprotection of aromatic acetates under very mild conditions. This method has been used for the protection of the hydroxy groups as well as for the deprotection of the acetates of several naturally occurring bioactive phenolic compounds. The catalyst can be easily
