Activation of Aryl Halides by Triplet–Triplet Annihilation Upconversion Enabling Coupling Processes Under an Open‐to‐Air Environment

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
Triplet–triplet annihilation upconversion (TTA‐UC) performed inside supramolecular viscoelastic gels enables efficient CC and C–heteroatom coupling reactions under green LED irradiation in open‐air conditions. The gel network restricts oxygen diffusion, preserves triplet states, and allows aryl halide activation through upconverted excited states ...

Benzoannelation of 2-methylindole via 1-N-carboxy-2-methylindole dianion: a direct regiospecific route to substituted and annelated carbazoles

, 1998
A facile general route for substituted and annelated N-H-carbazoles 6 has been developed by regiospecific 1,2-addition of 1-N-carboxy-2-methylindole dianion 3 to acyclic and cyclic α-oxoketene dithioacetals 4 followed by cycloaromatization in the ...

Regulation of Porcine Hepatic Cytochrome P450 — Implication for Boar Taint

Computational and Structural Biotechnology Journal, 2014
Cytochrome P450 (CYP450) is the major family of enzymes involved in the metabolism of several xenobiotic and endogenous compounds. Among substrates for CYP450 is the tryptophan metabolite skatole (3-methylindole), one of the major contributors to the off-
