The Pyrimidone derivatives say, N arylidine 6 methyl 2 oxo 4 phenyl 1, 2, 3, 4 tetra hydro pyrimidone carbohydrazides 2a e were synthesized by condensation of Benzaldehyde derivatives with 6 Methyl 2 oxo 4 phenyl 1, 2, 3, 4 tetrahydro pyrimidone carbohydrazides 1 in good yield. The so called hydrazone were cyclocondensed with succinic anhydride to afford 16 methy l2 oxo 4 phenyl 1,2,3, 4 tetra hydro pyrimidone 5 carboxamido 5 oxo 2 aryl pyrrolidine 3 carboxylic acid 3a e. These 3a e on Mannich reaction with formaldehyde and morpholine offered 2 ary l16 methyl 2 oxo 4 phenyl 1, 2, 3, 4 tetra hydro pyrimidine 5 carboxamido 4 morpholinomethyl 5 oxopyrrolidine 3 carboxylic acid 4a e. Further 4a e on condensation with 1, 2 benzenediamine yield N 3 1H benzo d imidazol 2 yl 2 aryl 4 morpholinomethyl 5 oxopyrro lidin 1 yl 6 methyl 2 oxo 4 phenyl 1, 2, 3, 4 tetra hydro pyrimidine 5 carboxamide 5a e. Their structures were confirmed by elemental contents and spectral features. The antimicrobial activities of all three series have also been evaluated. The whole synthetic route is shown below.
