The Bargellini reaction is a chemical reaction discovered in 1906 by Italian chemist Guido Bargellini.[1] The original reaction was a mixture of the reagents phenol, chloroform, and acetone in the presence of a sodium hydroxide solution.[2] Prior to Bargellini's research, the product attributed to this multi-component reaction (MCR) had been described as a phenol derivative in chemistry texts at the time. However, Bargellini demonstrated that a carboxylic acid derivative was actually the correct structure.
Later, organic chemists have used the reaction as a general method of organic synthesis for highly hindered or bulky morpholinones or piperazinones from ketones (particularly acetone) and either β-amino alcohols or diamines.[3]
