✦ Synopsis

The novel reactions of quinolinium and pyridinium N-imines with cyclopentadienones are described.

The 1,3-dipolar addition reactions of pyridinium N-imines and related ylides with activated acetylenes provide a useful method to synthesize nitroqenbridged heterocycles.

1 In recent years these reactions have been extended to cyclopropenones and yielded some interesting results.
