Abstract

Tetracyclo [10.3. 1.0. 1, 10.0. 2.7] hexadeca-2 (7), 9-diene-8, 14-dione 7 and tetracyclo [10.2. 2.01, 10027] hexadeca-2 (7), 9-diene-8, 13-dione 8 have been prepared through acid- catalysed intramolecular cyclisation of the diazomethyl ketones 19 and 25 respectively. The compound 7 is a skeletal representative of several tetracyclic diterpenes.
