iron(III) triflimide allowed the efficient thiolation of a range of arenes, including anisoles, phenols, acetanilides, and N-heterocycles. The method was applicable for the late-stage thiolation of tyrosine and tryptophan derivatives and was used as the keystep for the synthesis of pharmaceutically relevant biaryl sulfur-containing compounds such as the antibiotic dapsone and the antidepressant vortioxetine

intermolecular oxidative annulation of N-arylthio phthalimide derivatives with alkynes is showcased at room temperature. The annulation involves oxidative cleavage of the SN bond and the occurrence of 1,2-S-migration, which eventually allows the construction of diverse arrays of -conjugated 6-substituted 2,3-diaryl benzo[b]thiophenederivatives.
The enantioselective construction of axially chiral compounds by electrophilic carbothiolation of alkynes is disclosed for the first time. This enantioselective transformation is enabled by the use of a Ts-protected bifunctional sulfide catalyst and Ms-protected ortho-alkynylaryl amines (Ts=tosyl; Ms=mesyl). Both electrophilic arylthiolating and electrophilic trifluoromethylthiolating reagents are
首次公开了通过炔的亲电碳硫基化对轴向手性化合物的对映选择性结构。通过使用Ts保护的双官能硫化物催化剂和Ms保护的邻炔基芳基胺(Ts =甲苯磺酰基; Ms =甲磺酰基),可以实现这种对映选择性转化。亲电芳基硫醇化试剂和亲电三氟甲基硫醇化试剂均适用于该反应。轴向手性乙烯基-芳基氨基硫化物的所得产物可以容易地转化为联芳基氨基硫化物,联芳基氨基亚砜,联芳基胺,乙烯基芳基胺和其他有价值的双官能化化合物。
