In our studies, the organocatalytic 1,3-dipolar cycloaddition between 2-nitrobenzofurans or 2-nitrobenzothiophene and N-2,2,2-trifluoroethyl-substituted isatin imines has been developed. The reaction has been realized by employing bifunctional organocatalysis, with the use of squaramide derivative being crucial for the stereochem. efficiency of the process. The usefulness of the cycloadducts obtained has been confirmed in selected transformations, including aromative and non-aromative removal of the nitro group. In the experiment, the researchers used many compounds, for example, 2-Nitrobenzofuran (cas: 33094-66-5Category: benzofurans).
2-Nitrobenzofuran (cas: 33094-66-5) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Category: benzofurans
