Chemistry Retrosynthesis

I recommend a combination of tables and graphs for memorization.You should start immediately after you start learning reactions so you can add to them incrementally instead of trying to assemble a list of forty reactions the night before the final. This might seem tedious, but writing repetition helps most people learn.

Graphs should be developed for each starting functional group to illustrate the variety of products you can get in a single step. Graphs are particularly useful for recognizing more complicated reactions that form carbon-carbon bonds because you will better be able to recognize the underlying structures.

Tables are more complicated, but are also a good way to organize reactions.

The retrosynthetic analysis is not a synthesis form of organic chemistry, but an analytical approach based on the desired product.

The target molecule is broken down into smaller and smaller fragments.

Technically, you could draw out each arrow-pushing step to logically determine what product would emerge from a reaction, but who has the time?

It is far easier to memorize a few parameters for each reaction and use your limited exam time on other problems.Below you will find online available information resources on retrosynthesis and retrosynthetic analysis.

When planning laboratory synthesis of complex organic compounds, organic chemists, instead of choosing a starting material and then devising a path to convert it to the target compound, consider the target compound and identify an immediate precursor that can be converted to the target compound using a known reaction.The actual synthesis can then be designed based on the retrosynthetic analysis.The method of retrosynthetic analysis is very effective, but it requires a great knowledge of chemical compounds, classes of compounds, chemical reactions, reaction conditions etc.When you first try these types of problems, it will be bewildering to imagine all the possibilities.It can be particularly difficult for students who are able to do “forwards” problems easily on the first try because they are hesitant to choose a possibly incorrect path backwards and end up at a frustrating dead end.You will find that there are several different ways to complete the retrosynthesis, depending on which strategies you choose.University of East Anglia, UK Retrosynthetic Analysis Analysis of Complex Synthetic Problems; Terminology; Retrosynthetic Strategies; Goals and Subgoals; Computer-Assisted Retrosynthetic Analysis.
