Synthesis and biocidal activity of some new 2-amino-4,6-diaryl-substituted-pyrimidines

The chalcones (3a-q), derived from 3,5-dibromo-4-hydroxyacetophenone (1a), 3,5-dibromo-2-hydroxyacetophenone (1b), 3-bromo-5-chloro-/5-methyl-2-hydroxyacetophenones (1c,d) and 4-(4'-nitrophenoxy)acetophenone (1c) and prepared by Claisen-Schmidt condensation with different substituted aromatic aldehydes (2a-f) in presence of base, on treatment with guanidine nitrate in ethanol and base give new 2-amino-4,6-diaryl-substituted-pyrimidines (4a-q). The compounds have been screened for their antibacterial and herbicidal activities.

REACTION OF CHALOCONES WITH N-BROMOSUCCINIMIDE. SYNTHESIS OF AURONES

The reaction of 2'-OR-4-R1 chalcone with N-bromosuccinimide is reported.It was found that the structure of the product depends on the nature of the substituents R and R1.The prepared α-bromo-β-methoxydihydrochalcones were converted to the corresponding aurones.
