Summary, etc. |
<p class="Abstract">An environmental friendly, economical and clean Biginelli approach in presence of readily available <em>zinc</em><em> </em>acetate dihydrate<em> </em><em>(Zn(OAc)<sub>2</sub>.2H<sub>2</sub></em>O) to access biologically active 3,4-dihydropyrimidin-2-(1<em>H</em>)-ones/thiones derivatives <em>via</em> one-pot, three-component reaction of β-keto esters (methyl or ethyl acetoacetate), aromatic aldehyde (benzaldehye derivatives) and urea or thiourea in high to excellent yields has been studied. This solvent-free procedure is sustainable and advantageous compared to conventional methods due to short reaction times, one-pot procedure, easy handling, efficient, environmentally benign nature, low-cost and non-toxic catalyst, eco-friendly, ready availability of starting materials and no requirement of chromatographic purification. The products have been characterized by melting points and <sup>1</sup>H NMR spectroscopy.</p> |
