Synthon Approach in Designing Organic Synthesis

Synthon approach is a very useful analytical tool. It is an analytical approach to Organic Synthesis in which the target molecule is broken into fragments through a series of logical disconnection to get the best plausible and likely starting materials (ie. synthons or building blocks) for the target molecule. Synthesis is the real test of the organic medicinal chemist to use and control organic reactions. In each case the starting material is converted to some desired compound, the target molecule through some key intermediate. Actually, a number of synthetic routes can be written for a given target molecule. But in actual synthesis, generally that route is selected which is economical, safe, and easy to carry out and produces maximum yield in a short reaction time.
