Nitrile Oxides, Nitrones and Nitronates in Organic Synthesis: Novel Strategies in Synthesis

DOI: 10.1055/s-0036-1589042

N-Sulfonyl ynamido-phosphonates were prepared from sulfonamides and bromo alkynylphosphonates through a direct copper-catalyzed coupling reaction. The substrates were obtained in good to excellent yields. The latter are valuable partners to react with nitrile-oxides­ to form isoxazoles in good yields and with an exclusive regio­selectivity.
