Descrição geral

Methylenebis(phosphonic dichloride) is an organophosphorus compound that is commonly used in phosphonylation reactions. It is more reactive and the rate of reaction is faster compared to POCl3. This is because the phosphorus center is more electrophilic due to the lack of electron back-donation from the CH2 group.

Aplicação

Methylenebis(phosphonic dichloride) may be used for the following studies:
  • Synthesis of mycophenolic methylenebis(phosphonate) derivatives.
  • Phosphonylation of nucleosides.
  • Preparation of P,P′-partial esters of methylenebisphosphonic acid.
  • Synthesis of symmetrical di- and tetra- esters of methylenebisphosphonic acid.

Novel mycophenolic adenine dinucleotide (MAD) analogues have been prepared as potential inhibitors of inosine monophosphate dehydrogenase (IMPDH). MAD analogues resemble nicotinamide adenine dinucleotide binding at the cofactor binding domain of IMPDH; however, they cannot participate in hydride transfer and therefore

A new transformation of methylene-bis(phosphonic dichloride) into tetrathiobisphosphonate derivatives is reported. The reaction of methylene-bis(phosphonic dichloride) with 1,2-ethanedithiol in bromoform in the presence of AlCl(3) formed methylene-bis(1,3,2-dithiaphospholane-2-sulfide), which gave rise to O,O'-diester-methylenediphosphonotetrathioate analogues 1a-k upon reaction with phenols and alkyl

CD73 inhibitors are promising drugs for the (immuno)therapy of cancer. Here, we present the synthesis, structure-activity relationships, and cocrystal structures of novel derivatives of the competitive CD73 inhibitor α,β-methylene-ADP (AOPCP) substituted in the 2-position.
