Preparation of the library of fluorescent aromatic aminophosphonate phenyl and benzyl esters

Classical hydrophosphonylation of Schiff bases have been used for the preparation of library of diphenyl and dibenzyl aromatic aminomethylphosphonates N-substituted with aromatic moieties. The reaction, although being capricious provided the desired products in satisfactory yields. When using harsh reaction conditions conversion of diphenyl esters into monophenyl ones was observed. On the other hand, the use of more delicate conditions resulted in lack of hydrophosphonylation. The fluorescence studies revealed that the obtained library could be used for the construction of diagnostic microarrays.

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.

Radiolabelled bisphosphonates and method

The present invention relates to 32P or 33P-labelled bisphosphonates as radiotherapeutic radiopharmaceuticals. The 32P- or 33P-labelled bisphosphonates, which are chemically identical to the unlabelled agent, are expected to target the lesion site in an identical manner, but also deliver a significant radiocytotoxic effect to the surrounding cells. This should result, given the favorable energetics of the β particle emission from the 33P nuclide, in a loss of proliferative capacity of cells associated with the tumor lesion. The relative stability and in vivo localisation of bisphosphonates makes them good candidates as 32P/33P delivery vehicles.

Application of silicon-phosphorus based reagents in synthesis of aminophosphonates. Part 2: Reactions of N-(Triphenylmethyl)-aldimines with the silylated phosphorus acid esters

Reactions of silylated phosphorus acid esters with N-triphenylmethylaldimines (N-tritylaldimines) were investigated. N-Tritylmethaneimine reacts at room temperature with a mixture of P(OMe)3 and Me3SiBr forming the corresponding aminophosphonate derivatives in high yield. Other N-tritylimines are resistant toward the silylated reagents at room temperature, but undergo a similar phosphorylation reaction at elevated temperatures to form the expected aminophosphonic acids.
