Treatment of various dienimides in the presence of a Lewis acid and (trimethylsiloxy)furan leads to the corresponding aniline furan-2(5H)-ones. The same treatment with furan yields a triaryl product and, surprisingly, a byproduct with a pentacyclo[5.4.0.0.0.0]undecane main core. The formation of this birdcage system containing nine stereogenic centres was produced with complete diastereoselectivity
