Silver(I) triflate-catalyzed direct synthesis of N-PMP protected alpha-aminopropargylphosphonates from terminal alkynes.
[reaction: see text] N-PMP protected alpha-aminopropargylphosphonates have been synthesized by using a silver(I) triflate-catalyzed one-pot three-component reaction of terminal alkynes, p-anisidine, and diethyl formylphosphonate hydrate. Good to excellent yields of the desired products may be obtained with a very simple procedure.
