Aspirin is acetylsalicylic acid (o-acetoxybenzoic acid, \(\left.0-\mathrm{CH}_{3} \mathrm{COO}-\mathrm{C}_{6} \mathrm{H}_{4} \mathrm{COOH}\right)\); oil of wintergreen is the ester, methyl salicylate. Outline the synthesis of these two compounds from phenol.

To synthesize acetylsalicylic acid (aspirin) and methyl salicylate (oil of wintergreen) from phenol, follow these steps: 1. Convert phenol to salicylic acid via the Kolbe-Schmitt reaction with NaOH and CO2, followed by acidification with HCl. 2. Synthesize aspirin by reacting salicylic acid with acetic anhydride in the presence of a strong acid catalyst. $$\text{C}_{6}\text{H}_{4}(\text{OH})\text{COOH} + (\text{CH}_{3}\text{CO})_{2}\text{O} \rightarrow \text{CH}_{3}\text{COOC}_{6}\text{H}_{4}\text{COOH} + \text{CH}_{3}\text{COOH}$$ 3. Synthesize oil of wintergreen by reacting salicylic acid with methanol in the presence of a strong acid catalyst. $$\text{C}_{6}\text{H}_{4}(\text{OH})\text{COOH} + \text{CH}_{3}\text{OH} \rightarrow \text{CH}_{3}\text{OC}_{6}\text{H}_{4}\text{COOH} + \text{H}_{2}\text{O}$$
