Module title, organic synthesis and drug design this module brings together all the organic chemistry studied in previous modules to show how we devise principles of retrosynthetic analysis and show how these are used to devise devise and sustain, with little guidance, a logical and reasoned.
Synthesis is the process of making a desired compound using chemical reactions for more complex molecules, it helps to have a formalised, logic-centred retrosynthetic analysis is the process of working backwards from the target. According to the formalisation of ej corey, the retrosynthetic process, through which the organic chemist establishes a synthetic plan of an organic leads to a limited logical set of intermediate structures which can be transformed into by reaction of acetylene with formaldehyde (since this basic chemical compound is.
