Synthesis of Chemical Compounds

Synthesis of Chemical Compounds

• Synthesis Tasks:

  • 1) Synthesis of compounds from given reactants:

  • Combination A:

    • Reactants:
    • 3-Fluorobenzaldehyde (1 mol)
    • 3-Hydroxyacetophenone (1 mol)
    • Phenylhydrazine (1 mol)
    • Procedure:
    • Mix the reactants in a suitable solvent.
    • Heat under reflux condition to promote reaction.
    • Isolate the product via crystallization or filtration.

  • Combination B:

    • Reactants:
    • 2-Fluorobenzaldehyde (1 mol)
    • 3-Hydroxyacetophenone (2 mol)
    • Phenylhydrazine (1 mol)
    • Procedure:
    • Similar to Combination A, adjust the stoichiometry for 3-Hydroxyacetophenone.

• Synthesis Routes:

  • 2) Suggested synthesis route for specified compounds from given starting materials:
  • Example starting materials should be identified that have 6 or fewer carbon atoms.
  • Select appropriate reagents based on target compound requirements.

• Pyrimethamine Synthesis:

  • 3) Pyrimethamine is an antimalarial drug that inhibits dihydrofolate reductase in Plasmodium.
  • Starting Material: Toluene
  • Suggested Synthesis Route:
    • Introduce appropriate substituents and functional groups to convert to pyrimethamine.
    • Use reagents that contain 6 or fewer carbon atoms to ensure compliance with the requirement.

• Thiopental Synthesis:

  • 4) Thiopental is an anesthetic agent.
  • Starting Material: Diethyl malonate
  • Suggested Synthesis Route:
    • React with suitable reagents that contain 6 or fewer carbon atoms.
    • Follow the multistep approach to achieve the thiopental structure from diethyl malonate and selected reagents.
