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.

The reaction of 2-aryl-1,1-dibromocyclopropanes with adduct NOCl·(SO3)n leading to 3-aryl-5-bromoisoxazoles as a result of nitrosation—heterocyclization of the cyclopropane ring was studied. The reaction is accompanied with electroph

An efficient transformation of 2-aryl-1,1-dibromocyclopropanes under the action of sulfur trioxide activated nitrosyl chloride has been developed, providing a series of arylated 5-bromoisoxazoles with good yields. It is noteworthy that under the reported
