The first Pd-catalyzed C-H ethoxycarbonyldifluoromethylation with BrCF2CO2Et has been developed. The use of a bidentate phosphine ligand (Xantphos) is critical for the reaction to occur. A variety of electron-rich heteroarenes, including indoles, furans, thiophenes, and pyrroles, can be ethoxycarbonyldifluoromethylated in moderate to excellent yields. The reactions take place at the C-H bonds adjacent to the heteroatoms with high regioselectivity. This method provides a new protocol for the introduction of difuoroalkyl groups into electron-rich heteroarenes. In the experiment, the researchers used many compounds, for example, N-(2-(1H-Indol-3-yl)ethyl)acetamide (cas: 1016-47-3Formula: C12H14N2O).
N-(2-(1H-Indol-3-yl)ethyl)acetamide (cas: 1016-47-3) belongs to indole derivatives. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Formula: C12H14N2O
