Chromanone compounds, pharmaceutical compositions containing them, methods of making them, and methods of using them including methods for treating disease states, disorders, and conditions associated with the inhibition of antigen presentation by HLA-DR.
An electroreductive arylation reaction of aliphatic and aromaticaldehydes as well as ketones with electro-deficient (hetero)arenes is described. A variety of cyano(hetero)arenes and carbonyl compounds, especially aliphatic aldehydes, have been examined, providing secondary and tertiary alcohols in moderate to good yields. Mechanistic studies, including cyclic voltammetry (CV), electron paramagnetic

that the pyridine-boryl radical generated in situ using 4-cyanopyridine and bis(pinacolato)diboron could be used as a bifunctional "reagent", which serves as not only a pyridine precursor but also a borylradical. With the unique reactivity of such radicals, 4-substituted pyridine derivatives could be synthesized usingα,β-unsaturated ketones and 4-cyanopyridine via a novel radical addition/C-C coupling

A mild and highly efficient method for the hydropyridylation of α,β-unsaturatedesters has been developed. This protocol provides the products smoothly with a wide substrate scope in an undivided cell under ambient conditions. Moreover, studies showed that the scope could be extended to other unsaturated compounds, including enones and aldehydes.

a telescoped flow strategy to access electronically differentiated bisaryl ketones as potentially new and tunable photosensitizers containing both electron-rich benzene systems and electron-deficient pyridyl moieties. Our approach merges a light-driven (365 nm) and catalyst-free reductive arylation between aromaticaldehydes and cyanopyridines with a subsequent oxidation process. The addition of electron-donating
