N-azinylpyridinium N-aminides: tandem reactions with alpha-halocarbonyl derivatives and analogs

Pyridinium-N-(2´-pyridyl)aminide was reacted with different α-halocarbonyl derivatives and related compounds. The method allows an easy preparation of several heterocyclic building blocks, all including the 2-aminopyridine moietyAuthor wish to thank C.I.C.Y.T. for financial support (Project PM97-0074) and the Universidad de Alcalá for a grant to one of us (R.R.)
