, p. 1369 - 1375 (2007/10/02)
The aziridines 3, 3a and 3b obtained by the cycloaddition of phthalimidonitrene to cyclopentadiene derivatives 2, 2a and 2b undergoes facile ring expansion, when treated with sodium hydride to give substituted pyridine derivatives 4, 4a and 4b respectively.Hydrazinolysis of the aziridines gives the cyclopentadiene derivatives through the intermediacy of N-aminoaziridines 5, 5a and 5b.Oxidation of the aziridines 3, 3a with lead tetraacetate gives the aziridine 6 and 6a.

5,8-Dimethyl-1-tetralone (11) yields the hindered pyrylium salts (12)-(14), which give the corresponding pyridines and pyridinium salts with ammonia and amines.Chroman-4-one affords the oxoniaphenanthrene perchlorate (17).The additional steric hindrance f
