Abstract

Four new macrocyclic polyaza‐crown compounds containing a triazole subcyclic group and two to five lipophilic hydrocarbon substituents have been prepared from the appropriate polyamine and N‐THP‐protected 2,5‐triazoledimethyl dichloride. N,N,N',N'‐Tetrabenzyltetraazabistriazolo‐18‐crown‐6 was prepared from N,N'‐dibenzylethylenediamine and N‐THP‐protected 2,5‐triazoledimethyl dichloride. Biscyclohexano‐bispyridono‐18‐crown‐6 was prepared from trans‐ 1,2‐cyclohexanediol and THP‐protected 4‐hydroxy‐2,6‐pyridinedimethyl ditosylate.
