Synthesis of functionalized α-CF3-α-aminophosphonates via Cu(I)-catalyzed 1,3-dipolar cycloaddition
摘要:
A convenient method for the preparation of alpha-CF3-alpha-aminophosphonates bearing alkynyl group at the a-carbon atom has been described. New alkynylphosphonates have been further utilized in the synthesis of functionalized triazole-containing alpha-CF3-alpha-aminophosphonates via copper-catalyzed (3+2)-cycloaddition to different organic azides.
