Intramolecular double cyclization between a cyclohexadiene-Fe(CO)3 complex and a pendantdiene yielded a tricyclic molecule containing a spirocenter, with defined relative stereochemistry of four contiguous carbon centers. The nature of the substituent on the pendantdiene moiety has a significant effect on the yield: an ester group leads to lower yield. The product has a conjugated cyclohexadiene

A model study is described on a new approach to the synthesis of diquinane and angulartriquinane systems, via iron-promoted tandem [6+2] ene-type double cyclization followed by ozonolysis and intramolecular aldol reaction.

Regio- and stereo- controlled routes to functionalised hydroisoindoles have been developed by reaction of aminodienes with unsaturated anhydrides or acid chlorides and subsequent elaboration of the DielsAlder adducts.
