Synthesis and reactions of some new substituted cyclo-hexenone tetrahydropyrimidine derivatives of expected biological activity

4-[P-chlorophenyl]-[4H]-6-[substituted styryl-cyclo-hexenonyl]- 1,2,3,4-tetrahydropyrimidine-2-thione [IV] and 5-[p-chlorophenyl]-[5H] [7-substituted styryl-cyclohexenonely]-1,2,3,4-tetrahydrothiazolo- [3,2a]-pyrimidine-3 one derivatives [V] have been synthesized. The 2- aryl-methylene [VI] and the 2-aryl-hydrazono-[VII] were also synthesized. Some of these compounds have been tested for their antimicrobial activity
