An anhydrous magnesium sulfate mediated solvent-free protocol is described for the synthesis of dihydropyrimidinones (Biginelli compounds) at ambient temperature.
A fast and efficient Biginelli synthesis of 3,4-dihydropyrimidin-2-(1H)-ones (or thiones) by the reaction of aromatic aldehydes, -dicarbonyls, and urea/thiourea using NaHSO4H2O/ultrasound system is presented. The reactions were carried out in refluxing n-hexane/CH3CN (2.5:0.5mL) to afford the products in excellent yields.

Trimethylsilyl chloride (TMSCl) was used as a Lewis acid to efficiently perform one-pot, three-components, Biginelli condensation reactions of aldehydes, 1,3-dicarbonyl compounds, and urea or thiourea. This resulted in simple one-pot synthesis of the corresponding 3,4-dihydropyrimidin-2(1H)-ones at room temperature with excellent yield.

5c, 6b, 7a, 8a, 11c, 13a, and 16a) showed micromolar inhibition constants (Ki values range from ∼20–80 μm). Compounds 1c, 2b, and 15a showed only weak inhibition. In silico docking was employed to investigate the binding mode of each enantiomer of the strongest inhibitor, 5c (Ki = 19 ± 9 μm), as well as 7a (Ki = 21 ± 10 μm), the strongest inhibitor of the pyrrole series, in the active site of IMP‐1.
