Synthesis problems are the ultimate test of organic chemistry knowledge. Advanced practice problems require you to work backwards: identify the target molecule, find a "disconnection" (a bond you can logically break), and work backwards to commercially available starting materials. The best retrosynthetic thinkers think in terms of synthons (idealized reactive fragments) rather than actual reagents.
