Your question is very general, and its hard to formulate a simple answer. Something I've noticed is pharmaceuticals often (but not always) contain multiple fused benzine rings, often with nitrogen atoms in the ring. Something to help you understand it is how these drugs interact with the body...

In order to obtain experimental verification of the above conceptions as to the mechanism of interaction of the primary and cyclohexadienyl radicals, the radiolysis of deuterated toluene C 4 H 5 CD 3 was studied at the temperature of liquid nitrogen. The addition to the benzene ring of a ...
This section is mainly concerned with ring-transformation reactions induced by nitrogen nucleophiles not previously discussed <1984CHEC>, as well as some novel chemistry involving nitrogen nucleophiles. A synthetic route to 1,4-diazepin-5-ones such as 227 has been crafted by the reaction of 4-...
Direct substitution of the azido group by methoxy occurs with sodium methoxide in methanol. Above 130掳C nitrogen is lost from the azido compounds and ring contraction occurs yielding the corresponding (cyanocyclopentadienyl)tricarbonylmanganese complexes....

Benzene is a widely used commodity chemical, which is currently produced from fossil resources. Lignin, a waste from lignocellulosic biomass industry, is the most abundant renewable source of benzene ring in nature. Efficient production of benzene from l
