Exploring the impacts of the vinylogous anomeric effect on the synchronous early and late transition states of the hydrogen molecule elimination reactions of cis-3,6-dihalocyclohexa-1,4-dienes

Ionically Tagged Magnetic Nanoparticles with Urea Linkers: Application for Preparation of 2-Aryl-quinoline-4-carboxylic Acids via an Anomeric-Based Oxidation Mechanism

“…One of the important subsets of the anomeric effect is the vinylogous anomeric effect. − In the vinylogous anomeric effect, donors interact with acceptors through double bonds . This phenomenon is responsible for the pseudoaxial orientation of the acyloxy group at C-3 in a glycal …”

A convenient method for synthesis of terpyridinesviaa cooperative vinylogous anomeric based oxidation

“…The VAE had been applied for the stereoelectronic supported interactions of unshared electron pairs to vacant antibonding sigma orbitals (n / s*) over four bonds (Scheme 3). [45][46][47][48][49][50][51][52][53] Katritzky et al by low temperature X-ray crystallography have been shown that facile C-N bond dissociation of the benzotriazole residue in compound C, have been related to a vinylogous anomeric effect (VAE) (Scheme 4). 54 Based on above mentioned facts, "cooperative anomeric and/or vinylogous anomeric based oxidation" terms represent a new mechanistic vision and major driving force for the oxidative aromatization of some susceptible heterocyclic molecules.…”

Synthesis of triarylpyridines with sulfonate and sulfonamide moieties via a cooperative vinylogous anomeric-based oxidation

“…In the vinylogous anomeric effect, as an important subclass of anomeric effect, electron transfer interactions occurred through C = C bonds. This phenomenon has attracted the attention of many researchers [91][92][93][94][95][96][97][98][99] . Vinylogous anomeric effect can control the chemical reactivity.…”
