An Efficient Synthesis and In Vitro Antimicrobial Screening of 2-Cyanoimino -4-aryl-6-(1,1'-biphenyl-4-yl)-3,4-dihydro-1H-Pyrimidines

An efficient synthesis of 2-Cyanoimino-4-aryl-6-(1,1’-biphenyl-4-yl)-3,4-dihydro-1H-pyrimidines from stryl-4-biphenylketones and cyanoguanidine in presence of sodium hydroxide has been described. Cyanoguanidine serves as N-C≡N source for the construction of desired cyanoiminopyrimidines. The structural assignments of the titled products were done accordingly to their spectra like Mass, FT-IR, Proton and Carbon-13 NMR spectroscopy. The more stable tautomeric form was ascertained using Computational frequency analysis. The tested microorganism profile of compounds exhibits significant antimicrobial activity.
