The synthesis of useful substances is, arguably, the most important activity of chemists. There is a never-ending demand for new, better, chemical products to sustain and improve our lives, e.

The principal method for devising synthetic routes was developed by Prof E. The process is much more complex that than this brief description suggests; for more details consult textbooks or your course notes.

Choose the family of compounds you want to work on, choose an "Easy", "Medium" or "Difficult" problem, and click the "Get Problem" button. Perfect for both graduate and post-graduate students, Hybrid Retrosynthesis provides new applied skills and tools to help during their organic synthesis courses and future careers, whilst simultaneously acting as useful resource for those setting tutorial and group problems, and as a helpful go-to guide for organic chemists involved in either industry or academia.

In retrosynthetic analysis, you start with the target and work backwards, Principles of retrosynthesis yourself "What could this target be prepared from, using a reliable reaction?

How To Use This Page: Smith About the book By table of contents Book description Designed to supplement existing organic textbooks, Hybrid Retrosynthesis presents a relatively simple approach to solving synthesis problems, using a small library of basic reactio Stereoselectivity is not included in these problems, except for the control of alkene geometry.

Although the set of reactions available is restricted, it includes many of the most synthetically valuable CC bond forming reactions and functional group interconversions. Many useful resources are freely available on the web; the following links are good starting points.

This clear, concise guide reviews the essential skills needed for organic synthesis and retrosynthesis, expanding reader knowledge of the foundational principles of these techniques, whilst supporting their use via practical methodologies.

Show more Designed to supplement existing organic textbooks, Hybrid Retrosynthesis presents a relatively simple approach to solving synthesis problems, using a small library of basic reactions along with the computer searching capabilities of Reaxys and SciFinder.

A wide variety of targets are included, but most contain oxygen functional groups, and relatively few contain other heteroatoms such as nitrogen and sulfur.

Reusch, Michigan State Of this page you can practise devising syntheses of relatively simple target molecules using the retrosynthetic analysis strategy.

Then analyse the subtarget in the same way, and continue in this fashion until you arrive at readily available starting materials.

On completing these problems you should be able to: The reactions that you can choose from are all polar reactions, no pericyclic or radical reactions are included.Simple retrosynthesis OH OBn base BnCl HO HO excess base Br Br excess NHBn OBn Br OBn BnNH2 O OA simple understanding of basic reactions (& the principles behind them)allows a rapid synthesis of this precursor.

Disconnection of Carbinols In the course of the retrosynthetic analysis of TM 1, we met the first example of disconnection with the participation of one functional group (Sect.Scheme ).

Abstract. A problem-solving approach to retrosynthesis is introduced. Basic principles for good disconnections are postulated. Examples of interconversion and disconnection of carbinols, alkenes, ketones and nitro compounds are discussed.
