Pyridine substituted naphthalenes (e.g., I-III) constitute a class of potent inhibitors of aldosterone synthase (CYP11B2). To overcome the unwanted inhibition of the hepatic enzyme CYP1A2, we aimed at reducing the number of aromatic carbons of these molecules because aromaticity has previously been identified to correlate positively with CYP1A2 inhibition. As hypothesized, inhibitors with a tetrahydronaphthalene

The invention provides compounds of the general formula (I) which are inhibitors of the human aldosterone synthase, and also pharmaceutical compositions containing these compounds, and the use of these compounds and other heteroaryl substituted quinolinone derivatives for the treatment of hyperaldosteronism and/or disorders or diseases that are mediated by 11 β-hydroxylase (CYP11 B1).
Discovery of a Thioxanthone–TfOH Complex as a Photoredox Catalyst for Hydrogenation of Alkenes Using
<i>p</i>
‐Xylene as both Electron and Hydrogen Sources
novel organic photoredox catalyst was discovered by simply adding a catalytic amount of TfOH as a co-catalyst to readily available thioxanthone. The new catalyst, 9-HTXTF, shows a sufficiently long singlet lifetime and adequately strong oxidation potential, as well as relatively facile photoexcitation, with applications in the hydrogenation and deuteration of carbonylated alkenes.
