Hetarenes with a bridge nitrogen atom. 6. Ambident properties of the oxazolo[3,2-a]pyridinium nucleus in reactions with nucleophiles: Prediction and experiment

Autor: K. Yu. Pasichnichenko, Eugene V. Babaev, D. A. Maiboroda

Publikováno v: Chemistry of Heterocyclic Compounds. 33:338-342

We have studied the problem of ambident opening of five-membered and six-membered rings of the heteroaromatic oxazolo[3,2-a]pyridinium cation. A quantum chemical SINDO1 calculation of the energies of isomeric adducts of this cation with nucleophiles

Ring cleavage reactions in the series of azoloazines with a bridging nitrogen atom (review)

Autor: Eugene V. Babaev, D. A. Maiboroda

Publikováno v: Chemistry of Heterocyclic Compounds. 31:1251-1279

Extensive data on the opening reactions of both the five- and the sir-membered fragments of the bicyclic structures of azoloazines with a bridging nitrogen atom (i.e., the aza, oxa, and thia heteroanalogs of indolizine), including the reactions leadi

Hetarenes with a nitrogen bridging atom 1. Phenacylation of 2-substituted 6-methylpyridines

Autor: A. V. Efimov, D. A. Maiboroda, Eugene V. Babaev

Publikováno v: Chemistry of Heterocyclic Compounds. 31:962-968

The reaction of 2-X 6-methylpyridines (X = Cl, Br, OMe, OH, ONa) with phenacyl bromides has been studied. It was shown that for X = Cl or Br the reaction products unexpectedly proved to be the previously unknown 5-methyl homologs of oxazolo[3,2-alpyr
