Abstract

The acid catalyzed acetalization of 2,6-bis(2-hydroxyethoxy)benzaldehyde (4) is studied under various conditions. New 2,3-dihydro-5H-1,4-benzodioxepin derivatives are prepared and a fourteen-membered tetraoxy-genated macrocycle is obtained in 81% yield without special synthetic expedients. The solid state molecular structure of the macrocyclic compound is determined by single crystal X-ray analysis. © 1995 Elsevier Science Ltd.
