The aim of this work was the synthesis of polyaromatic systems by cyclization of β-polycarbonyls. Useful synthons for β-polycarbonyl derivatives are branched 1,4-dienes generated by cobalt-catalyzed hydrovinylation of terminal alkenes and 2,3-dimethyl-1,3

The combination of two powerful cobalt-catalyzed carbon-carbon bond forming transformations, namely, the Diels-Alder and the 1,4-hydrovinylation reaction, in a tandem or a sequential one-pot procedure, opened up a concise and efficient route to polysubstituted aromatic systems and cyclohex-3-enone derivatives. Furthermore, ozonolysis of the latter products led to polycarbonyl compounds with tailored carbonyl group distances which could be characterized via their respective BF2-borinane complexes. The cobalt catalysts tolerated several functional groups, and a flexible approach to polyfunctionalized compounds in concise fashion was described.
