  • Patent number: 4328343
    Abstract: A method of synthesizing fused ring pyridines (annulated) by co-oligomerization of .alpha.,.omega.-diynes with about molar equivalents of nitriles using a Co.sup.+1 catalyst preferably cyclopentadienyl cobalt dicarbonyl. Additionally, new compounds of tricyclic quinolizine-4-ones were produced where excess cyanoacetic ester starting materials were utilized (about 2:1 equivalent nitriles:diyne). The results with the catalyst employed indicated a stepwise mechanism in which cobalt(I) catalyst first forms a metallocycle intermediate derived from the bisacetylene. This cobalt(III) intermediate reacts preferentially with nitriles to give the product annulated pyridines in good yield. Generally, preferred conditions indicated roughly molar equivalents of reactants with no substantial excess of either reactant for the bicyclic compounds.
