Some new macrocyclic dibenzotrioxadiamides, trihenzotrioxadiamides and tetrabenzohexaoxatetraamide (1-9) have been prepared. Compounds (2-9) were obtained in the ~yclization step by reacting the dicaxboxylic acid dichloride (13) with appropriate diamine in CH2C12. The cyclization does not require high dilution techniques or ~mpla~ effect and provides the expected dilactams in high yields, ranging from 80% to 95%. However, the reaction of diamine (14a) with dicarboxylic acid dichloride (13) in high dilution conditions yielded the mixture of dilactam (2) and tetralactam (1) in moderate yields.
