Resumen

ZARE, Abdolkarim et al. Efficient Synthesis of 12-Aryl-8,9,10,12-tetrahydrobenzo[α]-xanthen-11-ones using Ionic Liquid Pyrazinium Di(hydrogen sulfate) {Py(HSO4)2} as a Novel, Green and Homogeneous Catalyst. J. Mex. Chem. Soc [online]. 2012, vol.56, n.4, pp.389-397. ISSN 1870-249X.

An efficient and simple solvent-free procedure for the synthesis of 12-aryl-8,9,10,12-tetrahydrobenzo[α]-xanthen-11-one derivatives via the one-pot multi-component condensation of dimedone with aromatic aldehydes and β-naphthol in the presence of protic acidic ionic liquid pyrazinium di(hydrogen sulfate) {Py(HSO4)2} as a green and homogeneous catalyst is described. All reactions proceed efficiently, and the title compounds are produced in high yields and in short reaction times.
