These compounds were obtained in the macrocyclization step by reacting the diamines 6 and 7 with appropriate dicarboxylic acid dichlorides 8-14. The cyclization does not require high dilution techniques or template effect and provides the expected dilactams in high yields ranging from 63% to 81%. %U https://ijcce.ac.ir/article_10199_3f0816a9e5003cff873ee9a0e8775719.pdf
