- Synthesis and properties of bicyclic aziridines, derivatives of triacetoneamine
-
Bicyclic aziridines, derivatives of 2,2,6,6-tetramethyl-4-piperidone (triacetoneamine), are synthesized, which by acids treatment undergo the N-C(1) or N-C(2) bonds cleavage to form the corresponding pyrrolines, pyrrolidines, and piperidines.

- Synthesis of terminal-biradical compounds consisting of two N-oxyl groups connected with conjugated π-systems
-
Terminal-biradical compounds 1 having two N-oxyl groups connected with conjugated π-systems were synthesized by (1) addition of magnesium acetylide to 4-oxo-TEMPO, followed by dehydration, or (2) cross-coupling between acetylene and vinyl triflate derived from 4-oxo-TEMPO.
