- Synthesis of 3,5-diarylisoxazoles under solvent-free conditions using iodobenzene diacetate
-
A simple and efficient method has been developed for conversion of chalcone oximes to 3,5-diaryl isoxazoles in excellent yields under solvent-free conditions. The synthesized compounds were characterized by infrared spectroscopy, 1H NMR, 13C NMR and HRMS.

- Efficient and regioselective one-pot synthesis of 3-substituted and 3,5-disubstituted isoxazoles
-
(Figure Presented) A series of 3-substituted and 3,5-disubstituted isoxazoles have been efficiently synthesized in moderate to excellent yields by the reaction of N-hydroxyl-4-toluenesulfonamide with α,β-unsaturated aldehydes/ketones. This novel strategy is associated with readily available starting materials, mild conditions, high regioselectivity, and wide scope.
