For Retrosynthesis

Reaction prediction and retrosynthesis are the cornerstones of organic chemistry. Designer a retrosynthetic analysis tool utilizing automated retrosynthetic rule generation, journal of chemical information and modelling (acs jcim) publication date (web) february 6, 2009 httpsen. The power of retrosynthetic analysis becomes evident in the design of a synthesis.

A retrosynthetic step involving the breaking of a bond to form two (or more) synthons. Department of physics and international center for quantum and molecular structures, shanghai university, shangda road 99, 200444, shanghai, china. This is achieved by transforming a target molecule into simpler precursor structures without assumptions regarding starting materials.

Unfortunately, powerful transform-based retrons are rarely present in complex molecules, and additional synthetic steps are often needed to establish their presence. A database may be consulted at each stage of the analysis, to determine whether a component already exists in the literature. Logic of chemical synthesis multistep synthesis of complex carbogenic molecules (nobel lecture) james law et.

Organisch-chemisches institut and center for multiscale theory and computation, westfälische wilhelms-universität münster, corrensstr. However, reaction rules often fail because they ignore the molecular context, which leads to reactivity conflicts. Rule-based expert systems have been the most widespread approach to computationally solve these two related challenges to date.

A nucleophilic -cooh group, and an electrophilic phch group. Often, a synthesis will have more than one possible synthetic route. A synthon and the corresponding commercially available the reverse of a synthetic reaction the formation of starting materials from a single product.

Each precursor material is examined using the same method. An example will allow the concept of retrosynthetic analysis to be easily understood. The application of transformations to retrosynthetic analysis can lead to powerful reductions in molecular complexity. Of course, both synthons do not exist per se synthetic equivalents corresponding to the synthons are reacted to produce the desired product. The identification one or more key bond disconnections may lead to the identification of key substructures or difficult to identify rearrangement transformations in order to identify the key structures.
