Abstract

Abstract: A novel dendrimer-9H, 9H, 11H, 11H, 12H, 12H-hexahydrobenzo[9,10]-1H, 1H, 3H, 3H, 4H, 4H, 5H, 5H, 7H, 7H, 8H, 8H-dodecahydrophenanthrene-2,6,10-trione ketal-tri-(4-(4-(3-(9-(4-(2,6-disulfo-cyclohexyl)phenyl))-2,4,8,10-tetra-oxa-spiro[5.5]undecyl))phenyl-1,1-(2,6-dioxa)cyclohexanedimethanol was conveniently synthesized by the reaction of hexahydrobenzo[9,10] dodecahydrophenanthrene-2,6,10-trione ketal-tri-2,2-dihydromethyl-1,3-propanediol with 4-(4-(3-(9-(4-(2,6-disulfo-cyclohexyl)phenyl))-2,4,8,10-tetra-oxa-spiro[5.5]undecyl))phenyl-1,1-(2,6-dioxa)cyclohexanedimethanol. Some reaction intermediates were prepared with common chemical reagent . Novel dendrimer and intermediates were identified via IR, ¹H NMR and MS spectra and elemental analysis.
