The actions of many infectious diseases are demanding due to fighting to antimicrobial agents. The emergence of fighting among bacteria to a wide variety of structurally unrelated antibacterial agents such as 6-lactams, macrolides, tetracyclines and fluoroquinolones as well as selected dyes and disinfectants has become a serious public health concern so makes it necessary to continue the search for new antibacterial agents. In recent scenario heterocycles is the different rule in drug synthesis. In that respect pyrimidine plays a significant rule among other heterocycles. From the literature survey, in modern years 1,2,3,4-tetrahydropyrimidines have engrossed significant awareness because of their therapeutic and pharmacological properties. more than a few of them have been found to demonstrate a wide spectrum of biological effects including antimicrobial, antitumour, antiviral, antihypertensive, alpha-1a adrenergic antagonist, neuropeptide antagonist.
