Synthesis of Indole Derivatives via Aryl Triazole Ring-Opening and Subsequent Cyclization
MoleculesA metal-free two-step synthetic approach for obtaining indole derivatives from aryl triazole fragment-containing compounds has been developed. In the first step, the Dimroth equilibrium, followed by nitrogen extrusion, Wolff rearrangement, and amine ...

Advanced Synthesis &Catalysis, EarlyView.A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

Advanced Science, EarlyView.This study explores how iron and manganese oxides transform sewage sludge into plant biostimulants during composting. Non‐targeted identification reveals the main species of plant biostimulants. Metagenomic analysis reveals that 2‐line ferrihydrite specifically enriches microbial genes for biosynthesis, boosting plant‐growth promoters.

Studies of Tryptophans in Membrane- Spanning WALP Peptides by Deuterium NMR Spectroscopy [PDF]
, 2000 WALP pep tides of sequence acetyl-Gly-Trp-Trp-(Leu-Ala)-Trp-Trp-Ala-ethanolamine insert into lipid bilayers as membrane-spanning a-helices and modulate the lipid phase behavior as functions of n and the lipid acyl chain length.
