The C2-symmetric 5,6-bis(benzyloxy)cyclohexa-1,3-diene and the corresponding tricarbonyliron complex have been synthesized in enantiomerically pure form. Reaction of the complex with trialkylaluminium gave a mono-alkylated product accompanied by racemization.

The 7,8-bis(benzyloxy)bicyclo[2.2.2]octa-2,5-diene derivatives have been synthesized via Diels-Alder reaction of optically active 5,6-bis(benzyloxy)cyclohexa-1,3-diene and dienophiles. The corresponding tricarbonylironcomplexes have also been synthesized in enantiomerically pure form.
