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 2'-Hydroxychalcone Dibromides with Me2SO

2'-Hydroxychalcone dibromides on treatment with Me2SO gave 2'-hydroxychalcone, 2'-hydroxy-3'- or 2'-hydroxy-5'-bromochalcone, flavone, monobrominated flavone, 6,8-dibromoflavone, 3-bromoflavone, and 3-, 6-, or 8-dibromoflavone.
