NAVARRO D, Camilo A; SIERRA, Cesar A y OCHOA-PUENTES, Cristian. Aqueous citric acid as green reaction media for the synthesis of octahydroxanthenes. Rev.Colomb.Quim. [online]. 2013, vol.42, n.2, pp.5-11. ISSN 0120-2804.
A simple, convenient and environmentally friendly one-pot procedure for the synthesis of 1,8-dioxo-octahydroxanthenes by the reaction of dimedone and aromatic aldehydes in aqueous citric acid is described. In this green synthetic protocol promoted by the reaction media, the use of any other catalysts and hazardous organic solvents are avoided, making the work up procedure greener and easier. The isolation of the products, obtained in good yields, is readily performed by filtration and crystallization from ethanol when required and the aqueous acidic media can be easily recycled and reused several times without significant loss of catalytic activity.
Palabras clave : Citric acid; dimedone; green synthesis; octahydroxanthenes.
