Choose routes that avoid competing reactions and protection steps. Practice Problem: Multistep Synthesis
Elias spent the next hour running the reaction again. He kept the stereochemistry of the epoxidation in mind, but when he hit the rearrangement step, he didn't panic. He used the steric hindrance to his advantage, guiding the rearrangement to the only stable conformation possible.

Key concepts
These resources provide peer-reviewed, graduate-level problems with full solution keys: advanced organic chemistry practice problems
Number the carbons in both the starting material and the product. Identify exactly which bonds are broken and which new bonds are formed.
In advanced organic chemistry, you aren't just predicting a product; you are deconstructing a target molecule (TM) back to commercially available starting materials. Choose routes that avoid competing reactions and protection
This is the Sudoku of chemistry. You are given a starting material (perhaps benzene) and a complex target (perhaps a polysubstituted aromatic ring with specific meta/para directors).
