Plication of compounds ()Qn)-(XXII) and conversion from a cation Z to an other Z, or from a metal to another one, can be performed by a three-step se-quence treatment with benzoyl chloride, reaction with sodium ethoxide and treatment with a transition metal t in presence of ZBr or Z Br. All the compounds of the type (Xni)-(XXII) can be transformed to the corresponding neutral compounds (x=0) after treatment widi an oxidizing reagent (e.g. Bt2) or by electrooxidation. 

For reaction at the amine unit, the carboxyl unit must be blocked. A solution of 53 in aqueous hydroxide will give 87, the carboxylate anion that has a free amine unit. If 87 reacts with an acid chloride such as benzoyl chloride, reaction with the nucleophilic amine group will generate an amide, 88 after esterification. Aqueous acid hydrolysis of the ester group in 88 gives the amide-acid 89.
