  The α-methyl- and β-methylcyclogeraniolenes, isolated by vapor-phase prepararative chromatography from the cyclisation products of dihydromyrcenes are described. Evidence, by NMR. and IR. spectroscopy, is presented for their structures. The γ-methylcyclogeraniolene is present in the cyclisation products to a very small extent if present at all.

• Ozonolyses of 4,4-Dimethyl-2-cyclohexen-1-yl Acetate and 4,4-Dimethyl-2-cyclopenten-1-yl Acetate. Competition between the Steric Effects of the Allylic Methyl Groups and the Electronic Effects of the Acetoxy Group on the Direction of Cleavage of the Primary Ozonides

  In order to understand the relative directing effects of the substituent steric and electronic effects on the cleavage of the primary ozonides, ozonolyses of a series of cyclohexene and cyclopentene derivatives were conducted in methanol or in ether in the presence of trifluoroacetophenone. The ozonolysis of 4,4-dimethyl-2-cyclohexen-1-yl acetate (1k) in methanol provided exclusively the alpha-methoxyalkyl hydroperoxide 7k derived from capture of 5-acetoxy-5-formyl-2,2-dimethylpentanal oxide by the solvent, while in the case of the relevant 4,4-dimethyl-2-cyclopenten-1-yl acetate (1l) the solvent-captured product 6l derived from trapping of 2-acetoxy-5-formyl-5-methylpentanal oxide was the major product. The remarkable difference in the regiochemistry of the fragmentation between the primary ozonides, 2k and 2l, is rationalized in terms of the significant difference in the steric congestion.

• DNA adducts and human atherosclerotic lesions

  It has been hypothesized that mutational events may be involved in the atherogenetic process and that at least a portion of atherosclerotic plaques may be the results of monoclonal proliferation of a single mutated smooth muscle cell (SMC). Therefore, atherosclerosis may be similar to carcinogenesis and may have an environmental etiology. We have analyzed bulky-aromatic DNA adducts in human thoracic aortas from mate subjects, aged between 30-60 years, who died suddenly or accidentally, and who had been examined by autopsy within 24 h after death. We found significantly (P < 0.001) higher DNA adduct levels in the samples from subjects with frequent atherosclerotic changes in the whole body ("Cases", N = 76) compared with those having few atherosclerotic changes ("Controls", N = 57). We also observed a significantly elevated weight of heart and plasma levels of total and LDL cholesterol in "Cases" vs "Controls". Significant differences in DNA adduct levels between smokers and nonsmokers were observed in "Controls" only. Multivariate linear regression analyses with age-adjusted data confirmed a significant influence of LDL cholesterol (P < 0.001), vitamin A (P < 0.01), smoking behavior (P < 0.05; evaluated as plasma cotinine levels) and NAT2 genotypes (P < 0.05) on bulky-aromatic DNA adduct levels. The induction of DNA adducts suggests that alterations at the DNA level may contribute to the development of atherosclerosis. Furthermore, atherogenesis and carcinogenesis may share a similar etiology, i.e. genotoxic action of environmental chemicals.
