Efficient synthesis of water-soluble, phosphonate-terminated polyester dendrimers

Simple and effective syntheses of novel, water-soluble, phosphonate-terminated polyester dendrimers varying in size and structure are described. These macromolecular compounds, consisting of thiophosphoric and 1,3,5-benzenetricarboxylic ester building blocks may find potential applications in health sciences as microbicides and/or as useful macromolecular models for functional coatings of superparamagnetic iron oxides (SPIOs) nanoparticles intended for use in hyperthermal therapy and magnetic resonance imaging (MRI). The dendrimers, possessing free phosphonate functional groups on the surface, were prepared in high yields from previously synthesized phosphorus-based substrates with 3,5-bis(dimethoxyphosphonyl)-methyl]benzoic acid (4), being an essential precursor of the dendrimer polyanionic surface. In addition, an interesting example of virtual coupling between remote nuclei in the 13C NMR spectrum of bisphosphonate monomer 3 was observed.

Synthesis of 3,5-bis(phosphonomethyl)benzoic acid and its application as a metal oxide surface bivalent anchor

A protected form of 3,5-bis(phosphonomethyl)benzoic acid (Bpb-OH), a metal oxide surface bivalent anchor, has been synthesized, coupled to an amine functionality, deprotected, and shown to bind to metal oxide surfaces. The protected anchor, 3,5-bis(dimethoxyphosphinylmethyl)benzoic acid (Me4Bpb-OH) was synthesized in 23% yield over four steps, coupled to a proline-chromophore, deprotected with a solution of iodotrimethylsilane (TMSI) in acetonitrile and adsorbed to Tin(IV)-doped indium oxide and nanocrystalline TiO2 electrodes at surface coverages of 1.5 x 10-10 mol cm-2 and 4.9 x 10-11 mol cm-2, respectively. Finally, Me4Bpb-OH was converted to an amino derivative by attaching a diamino butane linker.
