The syntheses of two phosphonic acids possessing the Fmoc-protected semicarbazide group are described. The key step was the Curtius rearrangement, performed in the presence of dibenzyl phosphonate esters. Preliminary experiments showed that the phosphonic acid can be grafted at the surface of oxide nanoparticles and colloidal zeolite nanocrystals, without deprotection of the Fmoc group.
