Popis: |
The heterocyclization of gem-dichlorocyclopropanes upon treatment with nitronium triflate in organic nitriles was studied and the influence of the medium on the reaction pathway was shown. While in anhydrous solvent 5-chloroisoxazole was the only product, the admixture with water promoted a three-component heterocyclization affording 4-chloropyrimidine N-oxides. This phenomenon was rationalized using DFT calculations. |
