The diastereoselective two-step synthesis of heterotricyclic systems is accomplished by regioselective cobalt-catalysed [4+2]- and [4+2+2]-cycloaddition reactions generating cyclohexa-1,4-diene and cycloocta-1,3,6-triene derivatives, and a hetero-Diels-Alder reaction. Thus, a set of selected cyclohexadienes and cyclooctatrienes were reacted with cyclic 1,3-diones and formaldehyde in a Knoevenagel-hetero-Diels-Alder multicomponent reaction to produce a variety of tricyclic products.
