The synthesis of derivatives of the hitherto unreported 3,9‐diazaspiro[5,5]undecane has been accomplished. Starting from the dianhydride of methanetetraacetic acid or from N‐methyl‐4‐piperidone, synthetic paths have been developed which permit the preparation of either symmetrical or unsymmetrical derivatives.
