Twelve new macrocyclic di- and tetraamides have been synthesized from the reaction of a bis(α-chloroamide) with a primary amine or with a diamine.Some of these cyclic di- and tetraamides contained pendant aminoalkyl groups attached on one or more ring nitrogen atoms.Two macrocyclic dithiadiamides were prepared from the reaction of a bis(α-chloroamide) and a dimercaptan.In every case, 12-, 14- and 15-membered cyclic di- and tetraamides were isolated in good yields.The 9-, 17- and 18-membered macrocycles were prepared in lower yields.Four of the amido-containing macrocycles were reduced by diborane to the peraza-crown compounds.
