[reaction: see text] A new methodology for the convergent synthesis of tetracyclic compounds was developed. Two new bicyclic Nazarov reagents of type II were synthesized, and their cycloaddition with 2-carbomethoxy-2-cyclohexenone I was studied. This cycloaddition afforded new interesting steroidal backbones.
