Preparation of a novel group of hybrid compounds N-benzyl aminoboronbenzylphosphonic and N,N′-ethylenedi(aminoboronbenzylphosphonic) acids

Two groups of new boronic acids containing aminophosphonate functions were synthesized and characterized by NMR spectroscopy and ESI-MS. Both groups of compounds were obtained by simple reactions of prepared in situ tris(trimethylsilyl) phosphite with a corresponding imine. The synthesized compounds may serve as a potential new class of building blocks, BNCT agents and supramolecular host molecules.
