electrochemically-assisted synthesis of (hetero)arylphosphonates from (hetero)arylhalides and dimethyl phosphite is described. Very mild and simple conditions are employed as the cross-coupling is carried out in galvanostatic mode, in an undivided cell at room temperature, using NiBr2bpy as the easily available pre-catalyst and acetonitrile as the solvent. In addition, both aryl bromides and iodides can be used
C–P bond formation of cyclophanyl-, and aryl halides <i>via</i> a UV-induced photo Arbuzov reaction: a versatile portal to phosphonate-grafted scaffolds
A new versatile method for the C–P bond formation of (hetero)aryl halides with trimethyl phosphite via a UV-induced photo-Arbuzov reaction, accessing diverse phosphonate-grafted arenes, heteroarenes and co-facially stacked cyclophanes under mild reaction conditions without the need for catalyst, additives, or base is developed. The UV-induced photo-Arbuzov protocol has a wide synthetic scope with large
3-phosphoindole compounds for the treatment of retroviral infections, and particularly for HIV, are described. Also included are compositions comprising the 3-phosphoindole derivatives alone or in combination with one or more other anti-retroviral agents, processes for their preparation, and methods of manufacturing a medicament incorporating these compounds.
