The synthesis of the racemates and the enantiomers of the 3,3‐disubstituted 2,6‐piperidinediones 3a – 3g is performed in three ways, depending on the C‐3 substituents. The 3‐cyclohexylpiperidinedione 3h is obtained as racemic and optically active compound by hydrogenation of the cyclohexenyl compound 3e with Pd/C. The N ‐methylpiperidinediones 7a and 7b are obtained by methylation of 3a and 3b with CH 2 N 2 .
