The Synthesis and Structural Design of Narcotic Compounds

1. Starting Material

Naloxone

2. Step 1: Reduction

Reagent: Sodium Borohydride (NaBH4)

Solvent: Ethanol or THF (Tetrahydrofuran)

Condition: Room temperature

Instructions:

1. Dissolve NaBH4 in ethanol or THF.

2. Add naloxone to the solution.

3. Stir the mixture at room temperature until the reaction is complete.

3. Step 2: Modify Structure

Remove Allyl Group

Reagent: Hydrogen Gas (H2)

Catalyst: Palladium on Carbon (Pd/C)

Condition: Hydrogenation vessel or high-pressure setup

Instructions:

1. Place the reaction mixture in a hydrogenation vessel.

2. Add Pd/C catalyst.

3. Introduce hydrogen gas and stir under pressure until the allyl group is removed.

Methylation

Reagent: Methyl Iodide (CH3I)

Base: Sodium Hydride (NaH)

Solvent: Anhydrous DMF (Dimethylformamide)

Condition: Elevated temperature

Instructions:

1. Dissolve sodium hydride in anhydrous DMF.

2. Add methyl iodide to the solution.

3. Heat the mixture to facilitate the methylation reaction.

4. Step 3: Final Adjustments

Formation of Ether Bridge

Reagent: Acid chloride or alkyl halide

Solvent: Anhydrous

Condition: As per specific reagent instructions

Instructions:

1. Add the appropriate reagent to the intermediate compound.

2. Stir under anhydrous conditions until the ether bridge forms.

Final Product

Morphine
