Abstract

A convenient synthesis of 26- to 28-membered thiamacrocyclic dilactams 8 was achieved via base-catalyzed condensation reaction of bis-2-cyanoacetamides 4 with dialdehyde derivatives 7. The reaction was assumed to be geometrically stereoselective, affording E, E′-configuration as the only isolable isomer. N, N′-[Alkanediylbis(thia-2,1-phenylene)]bis[2-cyanoacetamides] 4 were obtained by the reaction of cyanoacetic acid with the corresponding diamine hydrochlorides 3. © 2007 Wiley Periodicals, Inc.
