Silver‐Catalyzed One‐Pot Three‐Component Synthesis of α‐Aminonitriles and Biologically Relevant α‐Amino‐phosphonates
摘要:
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.
