A group of compounds which share a core motif, but have variations regarding functionality and positionality, can be described as a library of compounds. Beginning with simple building blocks starting materials can be gradually built up by a series of reactions with different reactants to produce a wide array of compounds. These compounds can retain the core motif that give the product the desired activity, but the increasing complexity of functional groups and side chains may lead to optimi...
