A general platform for the conversion of isoxazol-5-ones to 3,5-disubstituted isoxazoles has been developed via a two-step strategy. The first step leads to the formation of 5-(pseudo)halogenated isoxazoles, while in the second, a variety of heteroalkyl-, heteroaryl-, alkyl-, alkenyl-, alkynyl- and aryl-chains can be installed via nucleophilic substitutions or palladium catalyzed cross-coupling reactions.

A general method for isoxazoles from readily available ynones using trimethylsilyl azide as an amino surrogate, likely via an unprecedented hydroazidation of the alkyne and denitrogenative cyclization, is demonstrated. The method neither required any cata

3,5-Dimethyl-4-iodoisoxazole (1a) reacted with phenylacetylene with catalysis by palladium (II) chloride-triphenylphosphine complex to give 3,5-dimethyl-4-phenylethynylisoxazole (2a).When 1a was treated with styrene under similar conditions, 3,5-dimethyl-
