Stereoelectronic effects is a bridge between structure and reactivity. Anomeric effect plays an important role in the domain of stereoelectronic interaction and can be used for description of several unusual phenomena. Intramolecular negative hyperconjugation is also known as anomeric effect . In anomeric effect, both donor (lone pairs) and acceptor groups (electronegative elements) coexist in a proper molecule. This coexistence causes the acceptor groups to prefer the axial position in anomeric position [.
