Abstract

SALMON, Manuel et al. Contribution to the Biginelli Reaction, using a Bentonitic Clay as Catalyst and a Solventless Procedure. Rev. Soc. Quím. Méx [online]. 2001, vol.45, n.4, pp.206-207. ISSN 0583-7693.

The reaction of a set of five aldehydes, ethyl acetoacetate and urea or thiourea (Biginelli reaction) has been performed over a bentonitic clay as the catalyst, under solventless conditions using infrared irradiation as the energy source, obtaining the corresponding dihydropyrimidones .

Keywords : Biginelli esters; green chemistry; tonsil; bentonitic clay.
