CuCl2-mediated intramolecular C-H/C-H cross-dehydrogenative coupling (CDC) of thioalkyl-substituted α-acetyl or α-aroyl ketene N,S-acetals afforded 2-thioalkyl indoles. Tunable C-S bond transformations of the resultant indoles led to highly functionalized N-heterocyclic compounds. A β-thioalkyl is necessary to activate the N,S-acetal substrate and enable the CDC reaction to occur, and the relev...

The first total syntheses of spirobacillenes A and B were achieved concisely. The key transformation leading to spirobacillene A features a biomimetic intramolecular phenol-enol oxidative coupling reaction, and that leading to spirobacillene B highlights a bio-inspired intramolecular indole-ketone enolate oxidative coupling reaction.

An axially chiral N,N′-bisindole is shown on the cover picture, representing one of fruits tree indole chemistry. In their Research Article (e202300419), Yu-Chen Zhang, Feng Shi, and co-workers describe organocatalytic enantioselective construction scaffold with promising applications in medicinal chemistry asymmetric catalysis.

In the title compound, C(17)H(12)N(2), the inter-planar angle between the indole mean plane [max.deviation 0.030 (1) Å] and the phenyl ring is 24.32 (7)°. In the crystal, inter-molecular N-H⋯N C hydrogen bonds form zigzag chains in the a-axis direction augmented by weak C-H⋯N C contacts.

BACKGROUND The membrane permeability transition of mitochondria has been suggested to be involved in toxic and oxidative forms of cell injury. Mitochondrial dysfunction is considered to play a critical role in neurodegeneration in Parkinson's disease. Despite the suggestion that indole beta-carbolines may be neurotoxic, these compounds provide a protective effect against cytotoxicity of other n...
