Electrochemical Radical-Radical Cross-Coupling Approach between Sodium Sulfinates and 2 H-Indazoles to 3-Sulfonylated 2 H-Indazoles

A direct cross-coupling between sodium sulfinates and 2H-indazoles has been developed under electrochemical conditions. The utilization of a graphite anode and platinum cathode in an undivided cell with a constant current of 7 mA allowed the concurrent oxidations of sulfinates and 2H-indazoles to sulfonyl radical and radical cationic 2H-indazoles, facilitating the direct radical-radical coupling strategy to 3-sulfonylated 2H-indazole derivatives. The transition-metal- A nd redox-reagent-free synthetic approach should serve as a valuable synthetic tool to achieve heteroaromatic compounds.

Sulfonyl pyridine amide derivatives and preparation method thereof

The invention relates to a Sulfonyl pyridine amide derivatives and a preparation method thereof; the preparation method comprises the following steps: adding a compound as shown in a structural formula (II), a compound as shown in a structural formula (III), an oxidant, an additive and a heterogeneous biomass supported copper catalyst into a reaction container, adding a solvent, and carrying out astirring reaction at room temperature; and after the reaction is finished, filtering, extracting, concentrating, separating and purifying to obtain the sulfonyl pyridine amide derivative with the structural formula shown in the formula (I). The synthesis method of the sulfonyl pyridine amide derivatives is scientific and reasonable, and a series of sulfonyl pyridine amide derivatives are synthesized by a green and efficient synthesis method by adopting a heterogeneous biomass copper-loaded catalyst for catalytic reaction.

Switchable regioselection of C-H thiolation of indoles using different TMS counterions

A switchable regioselectivity in C-H thiolation reaction by simply swapping the counteranions of TMS is reported here for the first time. An exclusive C3-H thiolation of indoles with sodium arylsulfinates was achieved in the presence of TMSCl as a promoter. In contrast, with the use of TMSOTf instead of TMSCl under otherwise identical conditions, a regiospecific C2-H thiolation of indoles was realized with the same set of substrates.
