| Abstract: | Derivatives of decahydrophenanthridine-1,7-dione were obtained by the reaction of 2-acetyl-2-cyclohexen-1-ones with enamines of cyclic  -diketones (dihydroresorcinol, dimedone). Derivatives of hexahydroisoquinol-8-one having electron-acceptor substituents at the 4-position were obtained by the reaction of 2-acetyl-5,5-dimethyl-2-cyclohexen-1-one with acyclic enaminocarbonyl compounds. The reaction mechanism is discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 66–71, January, 1990. |
