The unique reactivity of sulfoxonium ylides as a carbene source is described for a variety of X-H bond insertions, taking advantage of a simple, commercially available iridium catalyst. This method has applications in both intra- and intermolecular reactivity, including a practical ring-expansion strategy for lactams. The safety and stability of sulfoxonium ylides recommend them as preferable surrogates to traditional diazo ketones and esters.

Provided herein are highly water soluble, thiazolidinone derivative compounds and glycine hydrazide derivative compounds that inhibit the ion transport activity of the cystic fibrosis transmembrane conductance regulator (CFTR). The compounds, and compositions comprising the compounds, described herein are useful for treating diseases, disorders, and sequelae of diseases, disorders, and conditions that are associated with aberrantly increased CFTR activity, for example, secretory diarrhea. The compounds may also be used for inhibiting expansion or preventing formation of cysts in persons who have polycystic kidney disease.
