Two Methylated Hexacyclic Cage Diketones

The structures of two methylated hexacyclic cage diketones, 1-methylhexacyclo[10.2.1.0^2,11.0^4,9.0^4,14.0^9,13]pentadeca-5,7-diene-3,10-dione, C₁₆H₁₄O₂, and 13,14-dimethylhexacyclo[10.2.1.0^2,11.0^4,9.0^4,14.0^9,13]pentadeca-5,7-diene-3,10-dione, C₁₇H₁₆O₂, have been determined. All bond lengths and angles are consistent with strained-cage geometry.
