Synthesis of sulfonamides from azoles and sodium sulfinates at ambient temperature

NBS or NIS mediated direct S[sbnd]N bond formation between azoles and sodium sulfinates is described. The reaction shows good substrate scope and tolerates a wide range of functionalities in both azoles and sodium sulfinate substrates. Pyrazoles are also suitable for this method, various 4-halopyrazoles derivatives were obtained by using N-halosuccinimide (NXS) as the halogen source.

Preparation method of N-substituted sulfonamide derivative

The invention discloses a preparation method of N-substituted sulfonamide derivative. The preparation method includes the following steps: taking NBS or NIS as an oxidizing agent; reacting an azole compound and sodium arylsulfinate in an organic solvent;

Pyrrole synthesis via allylic sp3 C-H activation of enamines followed by intermolecular coupling with unactivated alkynes

A conceptually novel pyrrole synthesis is reported, efficiently merging enamines and (unactivated) alkynes under oxidative conditions. In an intermolecular Rh catalyzed process, the challenging allylic sp3 C-H activation of the enamine substrates is followed by the cyclization with the alkyne (R3 = CO2R). Alternatively, in some cases (R 3 = CN), the enamine can be utilized for a vinylic sp2 C-H activation. A total of 17 examples with yields above 60% is presented, together with the results of an initial mechanistic investigation.
