Oxidation of longifolene with trilead tetraoxide in a mixture of acetic anhydride and glacial acetic acid was found to afford several products; longicamphenilone [1], longi-β-camphenilan aldehyde [2], longi-α-nozigiku alcohol [3], longiisohomocamphenilone [4], longihomocamphenilone [5], longi-β-nozigiku alcohol [6], and longi-β-camphenyllyl alcohol [7].
Their structures were assigned on the basis of their IR, NMR, and MS spectra.
