In connection with the syntheses of the A-ring analogs of tetracyclines, 2-carbamoylcyclohexane-1, 3-dione and its derivative, 2-methylcarbamoylcyclohexane-1, 3-dione, were synthesized by catalytic alkaline reduction of the corresponding resorcinol derivatives and their formation was established through analytical values and from ultraviolet and infrared absorption spectra.
