Here's some (i hope) good news about this hyterocyclic substance.....

US 3829429  Catalytic synthesis of substituted pyridines from acetylenes and nitriles

Cobalt-catalyzed pyridine synthese from alkynes and nitriles - Angew.Chem.Int.Engl. 17,505-515 (1978)

Cobalt-catalyzed synthesis of pyridiens from acetylenes and nitriles - Tetrahedron Letters No.36 p3383-3384 (1973)

First cobalt(I)- catalysed heterodyclotrimerization of theyne with nitriles to pyrides in water under mild conditions. - J.Chem.Soc. Chem. Comm. 1995 p179-180

and the site that started this whole search (

and the site that lead me to that (

I have been looking for this (potential) synth for a long time - just hope its realizable.
