Abstract
The reaction of 3,4-dihydro-N-oxo-3-ethyl-2,1-benzoxazinium salts with reagents with nucleophilic and basic character can be used to obtain β- or γ-substituted arylbutanes and trans-1-aryl-2-butenes. The reactions proceed regiospeciflcally and are regulated by the nature of the reagents used.
