A cycloaddition cascade between norbornene and 1,2-dicarbomethoxycyclobutadiene provides ready access to norbornyl-fused [n]-ladderanes, which undergo further cycloaddition to 1,3-cyclopentadiene to deliver arrays with norbornyl moieties at both the ends.

A short synthesis of norbornyl-fused [8]-ladderane is described.
