Conclusions

  1. 1.

    Certain α-aminoketones and nitrogen-substituted 3-aza-l,5-diketones were synthesized.

  2. 2.

    Cyclization of 3-aza-1,5-diketones to the corresponding unsaturated 3-ketopiperidones was carried out successfully in a benzene-aqueous base two-phase system in the presence of a phase-transfer catalyst.

  3. 3.

    N-methyl-and N-tert-butyl-5-tert-butyl-3-piperidones were synthesized.
