Organic synthesis is a special branch of chemical synthesis and is concerned with the intentional construction of organic compounds. Organic molecules are often more complex than inorganic compounds, and their synthesis has developed into one of the most important branches of organic chemistry. There are several main areas of research within the general area of organic synthesis: total synthesis, semisynthesis, and methodology. WebTOS and DOS are two very different approaches to organic synthesis, with different aims and scopes. If a specific target molecule for example offers properties of interest - such …
