Co-ordinated ether formation in the metal-directed condensation and macrocyclization of formaldehyde, ethanolamine, and a polyamine
Abstract
Reaction of formaldehyde, ethanolamine, and 1,10-diamino-4,7-diazadecane in the presence of CuII leads to the ready formation of the (1-oxa-1,6,8,12,15-penta-azatricyclo[13,3,1,18,12]icosane)copper(II) ion with the CuII bound by an ether oxygen and three amine donors, characterized by a crystal structure analysis.
