The corresponding 2-acetyl-1,3-cyclohexadien-1-ols were obtained by the reduction of 2-acetyl-3-chloro-2-cyclohexen-1-one and 2-acetyl-3-chloro-5,5-dimethyl-2-cyclohexen-1-one with zinc activated by silver acetate.They were studied in the Michael addition reaction with dimedone and 1,3-cyclohexanedione in the presence of sodium methoxide.It was concluded that the transformation of these 2-acetyl-2-cyclohexen-1-ones into the corresponding 2-acetyl-1,3-cyclohexadien-1-ols is reversible.By dehydration of the Michael addition adducts and reaction with ammonia tricycliccompounds with an additional pyran or dihydropyridine ring were obtained.
