A new chiral tetradentate compound has been prepared from (S)-2, 3-diaminopropanoic acid and 3-ethoxymethylenepentane-2, 4-dione and the corresponding nickel (II) and palladium (II) complexes have been characterized. The racemic form of the nickel (II) complex underwent template-controlled ring closure with 1, 3-diaminopropane to form a new 15-membered carboxylato-substituted macrocycle. In the presence of acid, this species ...
