A straightforward reaction sequence consisting of a cobalt-catalysed Diels-Alder reaction for the generation of dihydro-aromatic compounds and a rhodium- or alternatively a copper-catalysed CH-insertion reaction of carbenoids from diazo esters generates highly substituted benzene derivatives. When acyclic 1,4-dienes are synthesised by a cobalt-catalysed 1,4-hydrovinylation reaction, the rhodium-catalysed

[reaction: see text] The rhodium-catalyzed CH-insertion reaction of diazo ester derivatives into dihydroaromatic compounds was expanded to the application of various polysubstituted and functionalized 1,4-dienes generated from a cobalt-catalyzed Diels-Alder reaction. The highlyregioselective CH-insertion process produces after DDQ oxidation polysubstituted, polyfunctionalized aromatic compounds in
