AbstractA simple silver salt (AgSbF6)‐catalyzed aminophosphonylation and Strecker reaction have been developed and successfully applied to a wide range of substrates (>55 substrates). This solvent‐, ligand‐, and base‐free one‐pot three‐component protocol operates effectively at room temperature to provide diversified α‐aminophosphonates and α‐aminonitriles, which gave access to the respective α‐amino amides. Importantly, the present catalyst system is also capable to produce the rarely reported and biologically relevant aminophosphonates (having anti‐leishmanial activity). Further, mechanistic studies reveal that the present phosphonylation protocol follows a radical pathway.

Twenty-one a-aminophosphonates containing fluorine were synthesized by Mannich-type reactions. Their structures were established by elemental analysis, IR, 1H- NMR and MS. In field tests, some of these new compounds display high antiviral activity against the tobacco mosaic virus (TMV). The molecular geometry of compound 4f was determined by X-ray diffraction structure analysis.
