TRANSFORMATIONS OF CARBANIONIC ?-ADDUCTS OF 6-AZAQUINOXALINE DERIVATIVES
Ostrowski, Stanislaw,Makosza, Mieczyslaw
, p. 1721 - 1726 (2007/10/02)
Carbanions of α-haloalkyl aryl sulphones react with 6-azaquinoxaline via two pathways: the vicarious nucleophilic substitution of hydrogen and the bis-annulation.Factors governing these two reactions were analyzed and possibility of controlling the reacti
