Two crystalline minor products (14 and 15) were newly obtained by the oxidation of β-caryophyllene (1) with lead tetraacetate. The structures were determined as 4, 4-dimethyltricyclo-[6.3.2.02, 5]tridec-8-en-1-ol (14) and 4, 4-dimethyl-9-oxatetracyclo[6.4.2.02, 5.08, 10]tridecan-1-ol (15) by HR-MS, LR-MS, IR, 1H-NMR, 13C-NMR, and single crystal X-ray analysis data. Products 14 and 15 are novel sesquiterpenes.
