Abstract
A thorough NMR spectroscopic investigation was made on 7,12-dimethylbenz[a]anthracene (1) and the 1H- and 13C-NMR spectra were completely assigned. We compared the 13C-NMR chemical shifts (delta) of three benz[a]anthracenes, including compound 1, whose carcinogenicities vary largely, and investigated the relationship of the delta and carcinogenicity. It was found that the delta values at the C1, C2, and C6 positions differed significantly between the carcinogenic and noncarcinogenic compounds.
