12-chloromethyl-dehydroabie-tate reacts with 1-benzyl- and 1-arylimidazoles to give unsymmetrically substituted imidazolium chlorides (1a–i), with abietane moiety. Starting from methyl 12-aminodehydroabietate, symmetrically substituted diterpene-based salts of imidazolinium (4) and imidazolium (5) were synthesized. Anion exchange afforded corresponding (1e·BF4) and (1e·PF6). The new compounds were tested
