Versuchsvorschrift
350 mg of 7,7-dimethyl-6-methylene-tricyclo[6.2.1.01,5 ]undecan-2-one (see example 1) were heated at 40° for 5 days in the presence of 20 ml of 98% formic acid. After the usual treatments of extraction, washing, drying and evaporation, there were isolated 330 mg of crude material (purity 90%). The pure compound was obtained after cristallization in n-pentane.
