Neuroactive steroids in depression and anxiety disorders: Clinical studies [PDF]
Certain neuroactive steroids modulate ligand-gated ion channels via non-genomic mechanisms. Especially 3 alpha-reduced pregnane steroids are potent positive allosteric modulators of the gamma-aminobutyric acid type A (GABA(A)) receptor.

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

A Mild Disilane‐Enabled Halide‐to‐Deuterium Manifold With D2O for Aryl and Benzylic Halides
A broadly applicable Pd‐catalyzed dehalogenative deuteration enables efficient conversion of aryl and benzylic halides with inexpensive deuterium oxide (D2O). The method proceeds under exceptionally mild conditions without strong bases, harsh reductants, or stoichiometric Lewis acid halide scavengers, and tolerates a wide range of functional groups ...
