Have any of you guys heard of this mechanism? I saw it in a colledge book once, but the pictured only showed a secondary amine, with the same chain on
each side with carboxylgroups, and i think sodium ethoxide reacting to form a cyclohexane type structure...
Google kills my initiative with all those dam pdfs...
plus, most either talk
about pyridine type compunds being made from other rings. Any help would be appretiated

The amine itself has essentially nothing to do with the reaction. Try looking at,

As the Merk says, its an intramolecular claisen condensation. If you are after a mechanism, look up claisen.
Assume by pyridine compounds you mean fused to other rings (like a quinoline), rather than a seperate ring. This is a shame because I'm after a
good way to make pyridine.

Thats the one!, well, the second link to be exact, it looks exactly like the
reaction i saw... Thank you, that cleared up some questions i had about this method
Yeah, alot of the pdfs had chemicals like that quinoline, but sorry, i dont think i saw a route to pyridine,
dam adobe acrobat with the stupid load errors...

pyridines are normally made via a Hantsch synthesis
