4-Phenyl-1,2,4-triazolin-3,5-dione readily cycloadds to Nenitzescu's hydrocarbon 1 [6] with skeletal rearrangement. The major adduct 6 can conveniently be transformed to the azo compound 8, which upon photolysis or thermolysis yields up to 80 % pentacyclo[3.3.2.02,4,.03,7.o6,8]dec-9-ene (" snoutene ").
