Synthetic route design translates a retrosynthetic analysis into a practical, forward-executable sequence of reactions, weighing multiple competing criteria beyond simple chemical feasibility: overall step count and cumulative yield (since yield losses compound multiplicatively across a linear sequence), the cost and availability of starting materials and reagents, the compatibility of functional groups across the full sequence (requiring careful protecting-group strategy where a functional group must survive conditions that would otherwise react with it), and, for compounds intended for eventual scale-up, the practicality and safety of each step at production scale. A well-designed synthetic route for a medicinal chemistry programme additionally builds in structural flexibility at a late synthetic stage, allowing a common advanced intermediate to be diversified into multiple analogues for structure–activity relationship exploration without requiring a complete route redesign for every new compound.
