STUDIES ON THE SYNTHESIS OF HETEROCYCLIC COMPOUNDS. XVII. THE PREPARATION OF MACROCYCLIC POLYESTER LIGANDS CONTAINING THE 2,2'-BIS(HYDROXYMETHYL)DIPHENYLMETHANE SUBCYCLIC UNIT

Novel macrocyclic tetraester ligands containing the 2,2'-bid(hydroxymethyl)diphenylmethane subcyclic unit have been prepared using an intermediate dioxastannocin with diacyl chlorides.The products were characterized by analitycal and spectroscopic (IR and NMR) data.The MS spectra of these ligands have been studied and the fragmentation patterns and structures of the main ions are described.
