Synthesis of Natural Products and Pharmaceuticals
The synthesis of natural products and pharmaceuticals is a complex and fascinating field of chemistry that involves the design, development, and production of biologically active compounds. These compounds are often used to treat diseases, alleviate pain, and improve quality of life.
The synthesis of natural products and pharmaceuticals typically begins with the identification of a target molecule. This molecule may be a naturally occurring compound, such as a plant alkaloid or a marine sponge metabolite, or it may be a synthetic compound that has been designed to have specific biological activity. Once the target molecule has been identified, chemists must develop a synthetic route that will allow them to produce the compound in a cost-effective and efficient manner.
The synthetic route for a natural product or pharmaceutical will depend on a number of factors, including the target molecule's structure, reactivity, and availability of starting materials. Chemists must carefully consider each step of the synthesis to ensure that the final product is of high quality and purity. Common techniques used in the synthesis of natural products and pharmaceuticals include:
- Organic chemistry
- Organometallic chemistry
- Heterocyclic chemistry
- Solid-phase synthesis

Synthesis of Aspirin
Objective:
To synthesize aspirin (acetylsalicylic acid) and characterize it using various techniques.
Materials:
- Salicylic acid
- Acetic anhydride
- Sodium acetate
- Ethanol
- Water
- Melting point apparatus
- IR spectrophotometer
- NMR spectrometer
Procedure:
Synthesis of Aspirin:
