Synthesis of Large Macrocyclic Tetraaza Compounds with A Methylene Backbone: Cyclo4, (n = 6,7,8,9 and 10). The Formation of 28-, 32-, 36-, 40- and 44-Membered Rings.

A series of macrocyclic tetraamines with 28-, 32-, 36-, 40- and 44-membered rings have been efficiently prepared from the corresponding ditosylamide and monobromoalcohol derivatives in 6 steps via a double condensation reaction.Overall yields were: 41, 41, 46, 29, and 33 percent, respectively, for 1,8,15,22-tetraazacyclooctacontane (11a), 1,9,17,25-tetraazacyclodotriacontane (11b), 1,10,19,28, tetraazacyclohexatriacontane (11c), 1,11,21,31-tetraazacyclotetracontane (11d) and 1,12,23,34-tetraazacyclotetratetracontane (11e).
