The invention is concerned with the compounds of formula I and salts thereof and other compounds of formulas II-IX as disclosed herein. In addition, the present invention relates to methods of manufacturing and methods of using the compounds of formulas I-IX as well as pharmaceutical compositions containing such compounds. The compounds may be useful in treating diseases and conditions mediated by TRPA1, such as pain or asthma.
Their synthesis, optical purity, electronic properties, and catalytic behavior in the prototypical rhodium‐catalyzed 1,4‐addition of phenylboronicacid to 2‐cyclohexen‐1‐one are presented through an in depth study of this ligand class. Density functional theory calculations on the step of the catalytic cycle that determines the enantioselectivity are presented and reinforce the first hypothetical explanations
An NH transaction: The first direct synthesis of tertiary NH sulfonimidamides from tertiary sulfinamides by electrophilic NH transfer has been achieved. In vitro studies did not reveal any intrinsic flaw of the sulfonimidamide group regarding properties relevant to medicinal chemistry.

Heteroaromatic sulfoxides are a frequent structural motif in natural products, drugs, catalysts, and materials. We report a metal‐free visible‐light‐accelerated synthesis of heteroaromatic sulfoxides from sulfinamides and peroxodisulfate. The reaction proceeds at room temperature with blue‐light irradiation and allows the C−H sulfinylation of electron‐rich heteroarenes, such as pyrroles and indoles
