A series of methyl‐2,6‐diaryl‐1‐methyl‐4‐oxopiperidine‐3,5‐dicarboxylates Ia‐c and 2,4‐diaryl‐3,7‐dimethyl‐1,5‐dimethoxycarbonyl‐9‐bispidinones IIa‐c have been synthesized and studied by ir, 1 H and 13 C nmr spectroscopy and the crystal structure of methyl 2,4‐diphenyl‐3,7‐dimethyl‐9‐oxo‐3,7‐diazabicyclo[3,3.1]nonane‐1,5‐dicarboxylate (IIa) has been determined by X‐ray diffraction. The enolic form of compound Ia (I'a) was also studied.
