Abstract

For the first time the possibility has been shown of recyclizing 1-alkyl-5-benzoyl-3-ethoxycarbonyl-6-methylthio-1,2-dihydropyridin-2-ones into 1,6-annelated bicyclic derivatives of 3-alkylcarbamoyl-5-benzoylpyridin-2-one, which takes place on reacting the former with 1,4- and 1,5-nitrogen-containing dinucleophiles. The structure of the recyclization products was demonstrated by spectral methods and X-ray structural analysis.
