## Abstract Methyl 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 (
