It was demonstrated that nitrosylsulfuric acid can be successfully used as a tandem nitrosating and oxidizing agent in the synthesis of 3,5-diarylisoxazoles from 1,2-diarylcyclopropanes. The reaction proceeds highly regioselectively in the case of symmetr
Nitrosylsulfuric acid as an oxidant in the synthesis of 3,5-diarylisoxazoles

By six examples, it was demonstrated that nitrosylsulfuric acid can be successfully used for oxidation of 3,5-diaryl-4,5-dihydroisoxazoles to the corresponding 3,5-diarylisoxazoles. If the starting isoxazolines contain the aromatic substituents activated towards electrophilic substitution, nitration of both newly formed isoxazole and substituted benzene rings occurred.

A collection of isoxazoles derivatives has been efficiently synthesized in three steps. The oximation reaction of aldehydes followed by nitrile oxide [3+2] 1,3-dipolar cycloaddition and MnO2-oxidation reaction furnished the title compounds which were purified by simple filtration on celite.

REACTION OF 1,2-DIARYLCYCLOPROPANES WITH COPPER NITRATE IN ACETIC ANHYDRIDE AS A METHOD FOR THE SYNTHESIS OF 3,5-DIARYLISOXAZOLES
Sychkova, L. D.,Shabarov, Yu. S.
, p. 261 - 264 (2007/10/02)
In the reaction of 1,2-diarylcyclopropanes with copper nitrate in acetic anhydride the only reaction path leads to the formation of 3,5-diarylisoxazoles.The course of the transformation is affected significantly by the configuration of the initial cyclopr
