Consider the following structure.
OH
Esmolol
The synthesis of this compound uses a building block derived from either ethylene oxide or epichlorohydrin.
1) Determine which building block was used: |
2) Draw the structure of the nucleophiles that were used along with this building block in the synthesis of the molecule.
• Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
You do not have to consider stereochemistry.
