Pyrimidine is a six member heterocyclic ring having two nitrogen (N) atom 1, 3 position. Chemistry of pyrimidine is a blossoming field. Various methods for synthesis of pyrimidine and also their diverse reactions allows enormous in the field of medicinal chemistry. Pyrimidine not only has a wide range of pharmacological and biological activities but there are several established protocols to synthesize this ring. Pyrimidine ring has been found to possess anti-malarial, anti-bacterial, antifungal, anticancer, anticonvulsant, anti-inflammatory, and analgesic activity. This book reports about...

The present work describes about the synthetic and biological aspects of Benzimidazole moiety. The benzimidazole moiety has been associated with vast biological effects on the body systems and further research has to be conducted to explore the possible outcomes. Many researchers have worked day and night to explore the potential of this moiety and also have reported the important synthetic schemes as well as the effecs along with mechanisms of the derive=atives designed both in silico and the wet labs.
