New 3-azidoalka-1,3-dienylphosphonates were synthesized by a convenient and efficient method. These compounds are useful as intermediates in the preparation of 3-(3-aryl-4,5-dihydroisoxazol-5-yl)- and 3-alkenyl-4-(diethoxyphosphoryl)isoxazoles. allenes - azides - isoxazoles nitrile oxides - phosphorus
