Some new sulfur macrocyclic diamides and tetraamides were obtained via a simple and convenient method. This method consists of reacting a dicarboxylic acid dichloride with the appropriate diamine in dichloromethane. The cyclization does not require high dilution technique or template effect and the expected dilactams were obtained in high yields.
