Nitrogen Containing Organic Compounds and Some Aspects of- Medicinal Chemistry

(Theory)

The students will be able to –

CO105: describe the structural and chemical properties of five and six membered aromatic heterocycles

CO106: learn the preparations and reaction mechanisms of benzofuzed heterocycles

CO107: discuss the formation and reactivity of aliphatic as well as aromatic nitro compounds

CO108: differentiate between 1°/2°/3° amines and discuss their role in acting as a base, phase transfer catalyst and as a precursor to diazotization

CO109: classify chemotherapeutic agents on the basis of their medicinal applications and define their structure, function and synthesis.
