We report a visible‐light photoredox‐catalyzed strategy for the divergent dual selenylation of inert C─H and N─H bonds. Using a single catalytic system with Ru(bpy)3Cl2·6H2O and diselenides, arylamines and indoles are selectively converted to distinct N,C‐ or C,C‐disubstituted organoselenides, respectively. ABSTRACT We report a visible‐light photoredox‐

Utilisation of alicyclic compounds by soil bacteria [PDF]
Alicyclic compounds are recalcitrant hydrocarbons, they are a major component of crude oil and their fraction in the oil may be as high as 37%. They are used as industrial chemicals and are obtained via extraction from petroleum or by synthesis. A number

(25R)-5a-Spirostane-3,12-dione
The title compound, C27H40O4, was obtained from the oxidation of (25R)-3b-hydroxy-5a-spirostan-12-one (Hecogenin) by Jone's reagent. The molecule contains six alicyclic and heterocyclic rings, all trans-fused, among which four six-membered rings adopt ...

Crystal engineering with alicyclic β-amino acids: Construction of hydrogen-bonded bilayers
The crystal structures of four homologous cis-alicyclic ß-amino acids present a new recurring layer pattern of hydrogen bonds. This pattern was derived from two one-dimensional patterns observed in related alicyclic 2-hydroxycarboxylic acid structures ...

Synthesis of Polycyclic Isoindolines via CH/NH Annulation of Alicyclic Amines
Relatively unstable cyclic imines, generated in situ from their corresponding alicyclic amines via oxidation of their lithium amides with simple ketone oxidants, engage aryllithium compounds containing a leaving group on an ortho-methylene functionality ...
