Principles of organic synthesis from "summary" of Chemistry for Pharmacy Students by Lutfun Nahar,Professor Satyajit D. Sarker
The principles of organic synthesis are fundamental to the design and production of organic compounds. Organic synthesis involves the creation of complex molecules from simple starting materials through a series of well-defined chemical reactions. These reactions are carefully chosen and executed to achieve the desired product in high yield and purity. One of the key principles of organic synthesis is retrosynthesis, which involves working backwards from the target molecule to identify the most efficient route for its synthesis. This approach allows chemists to plan the synthesis strategically, considering factors such as reactivity, selectivity, and practicality. Another important principle is selectivity, which refers to the ability to control the outcome of a reaction to produce the desired product selectively. Selective reactions are essential in organic synthesis to avoid side reactions and by-products that can decrease the overall yield and efficiency of the process. Chemoselectivity, regioselectivity, and stereoselectivity are different aspects of selectivity that chemists consider when designing synthetic routes. Chemoselectivity involves the preference of one functional group over another, regioselectivity determines the site of reaction in a molecule, and stereoselectivity controls the stereochemistry of the product. Furthermore, efficiency is a critical principle in organic synthesis, as chemists aim to maximize the yield of the desired product while minimizing waste and by-products. Efficiency can be achieved through careful selection of reagents, optimization of reaction conditions, and implementation of purification techniques.- The principles of organic synthesis provide a framework for chemists to plan and execute the synthesis of complex organic molecules. By understanding and applying these principles, chemists can overcome challenges and achieve success in the field of synthetic organic chemistry.
