Stereoelectronic Effects illustrates the utility of stereoelectronic concepts using structure and reactivity of organic molecules. This advanced textbook provides an up-to-date overview of the field, starting from the fundamental principles and presenting a large selection of modern examples of stereoelectronic effects in organic reactivity.

Definition: Stereoelectronic effects – interactions of electronic orbitals in three dimensions. The typical stereoelectronic effect involves an electronic interaction which stabilizes a particular conformation or transition state and is fully expressed only when the correct geometry is achieved. Caveat: “stereoelectronic” is not the same File Size: 8MB. Anomeric effect Last updated Janu The α- and β-anomers of D-glucopyranose.. In organic chemistry, the anomeric effect or Edward-Lemieux effect is a stereoelectronic effect that describes the tendency of heteroatomic substituents adjacent to a heteroatom within a cyclohexane ring to prefer the axial orientation instead of the less hindered equatorial orientation that would be.

Thatcher. Equally important, however, are three additional chapters that deal with the general consequences of the stereoelectronic interactions that are associated with the basis of the anomeric effect.
The remainder of the book is devoted to new areas of development in the The Anomeric effect and associated stereoelectronic effects book as differentiation of the endo and exo anomeric interactions.

Publication info: Washington, DC: American Chemical Society, The book has countless examples of stereoelectronic effects from the literature, but unfortunately, it never really introduces the theory behind it in a systematic way.
It essentially goes through examples of stereoelectronic effects, based on functional group, starting with the acetal.

Stereoelectronic interaction effects (associated with the anomeric effects) on the stability of the stereoisomers of 1,4,5,8-tetraoxadecalin, 1,4,5,8-tetrathiadecalin and 1,4,5,8-tetraselenadecalin.
An ab initio study and NBO analysis The most dominant conformation-controlling factor in carbohydrate compounds is known as anomeric effect (AE).Cited by: 7. The nature of the anomeric effect in the bicyclic trans-fused octahydromethyl-1H-2,1-benzothiazine 2,2-dioxide 37 has been examined by single crystal X-ray structure analysis (Figure 5).The crystal structure of 37 shows that the N-Me group assumes an axial position in the solid authors suggest that this conformation is also the most stable in solution and propose.
