Nitrosylsulfuric acid as a tandem reagent in the synthesis of 3,5-diarylisoxazoles from 1,2-diarylcyclopropanes

Аннотация

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 symmetric diarylcyclopropanes. The mixtures of regioisomeric 3,5-diarylisoxazoles were obtained from non-symmetric 1,2-diarylcyclopropanes.
