Abstract
  In the present study, we discussed that, the elemental bromine is a highly efficient and selective homogeneous Lewis acid catalyst for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones. Biginelli three-component condensation was carried out by the reaction of an aromatic aldehyde, urea/thiourea, and methyl/ethyl ...  Read More
