Abstract
Abstract An efficient synthesis of 1 starting from N,N′-bis(3-aminopropyl)ethylenediamine 2 is described. Two salient features of the present work are the selective bis or tris-trifluoracetylation of 2 and a novel bis-macrocyclization of the hexatosyl intermediate 5 using ethylene glycol ditosylate.
