Despite common occurrence in molecules of value, methods for transforming sulfonamides are distinctly lacking. Here we introduce easy-to-access sulfonyl pyrroles as synthetic linchpins for sulfonamide functionalization. The versatility of the sulfonyl pyrrole unit is shown by generating a variety of products through chemical, electrochemical and photochemical pathways. Preliminary results on the direct functionalization of primary sulfonamides are also provided, which may lead to new modes of activation.

((2S,4R)-4-Hydroxy-N-(2-methylnaphthalen-1-yl)pyrrolidine-2-carboxamide (HMNPC), an amide derived from 4-hydroxy-L-proline and 2-methyl naphthalen-1-amine, is a powerful ligand for Cu-catalyzed coupling of (hetero)aryl halides with sulfinic acid salts, allowing for first time the metal-catalyzed coupling of (hetero)aryl chlorides and NaSO2Me. A considerable number of (hetero)aryl chlorides worked well, providing the pharmaceutically important (hetero)aryl methylsulfones in good to excellent yields.

New compounds of formula 1 are provided which by virtue of their pharmaceutical activity as PI3-kinase modulators may be used in the therapeutic field for the treatment of inflammatory or allergic diseases. Examples of these include inflammatory and allergic respiratory complaints, inflammatory diseases of the gastro-intestinal tract and motor apparatus, inflammatory and allergic skin diseases, inflammatory eye diseases, diseases of the nasal mucosa, inflammatory or allergic conditions involving autoimmune reactions or inflammations of the kidney.
