featuring the 1,3-dipolarcycloaddition reaction of α-azido acrylates and aromatic oximes was developed. This procedure provides an efficient, straightforward and metal-free method for the synthesis of 3,4,5-trisubstituted isoxazoles under mild reaction conditions. A novel, one-pot, cascade reaction sequence featuring the 1,3-dipolarcycloaddition reaction of α-azido acrylates and aromatic oximes was
