Continuous Flow Nucleophilic Aromatic Substitution with Dimethylamine Generated in Situ by Decomposition of DMF

open access: yes, 2013
A safe, practical, and scalable continuous flow protocol for the in situ generation of dimethylamine from DMF followed by nucleophilic aromatic substitution of a broad range of aromatic and heteroaromatic halides is ...

Targeted keratin repair: A plant‐based approach to hair strength and surface restoration

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Application of Avena strigosa seed extract may reinforce keratin bonding, restoring hair fibre integrity by promoting intramolecular interactions at damaged sites of keratin proteins. Abstract Objective Chemical and thermal stress disrupts the intramolecular and intermolecular interactions that stabilize hair keratin, leading to structural degradation ...

Four Haylages, One Metabonome: Defining Diet Driven Metabolic Shifts in Ponies

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Haylage is widely fed to all categories of stabled horses across Europe and New Zealand. Haylage can vary from high energy nutrient dense forage to low energy highly fibrous fodder, yet little is known about the impact different haylages have on metabolism in horses.

Changes in urinary metabolome related to body fat involve intermediates of choline processing by gut microbiota

open access: yesHeliyon, 2019
Countering the obesity pandemic will require better understanding of disease mechanisms and development of new diagnostic methods. Small molecule metabolites excreted in urine can be important biomarkers of disease progression and treatment.

3-Hydroxy-3-[(2-methylpropanoyl)methyl]indolin-2-one

open access: yesActa Crystallographica Section E, 2009
The title compound, C13H15NO3, was synthesized by the Aldol reaction of isatin and 3-methylbutan-2-one refluxing in methanol catalyzed by dimethylamine. The packing of the molecules in the crystal structure features intermolecular N—H...O and O&

Simple, efficient protocols for the Pd-catalyzed cross-coupling reaction of aryl chlorides and dimethylamine [PDF]

open access: yes, 2009
Simple and efficient procedures for the Pd-catalyzed cross-coupling reaction of aryl chlorides and dimethylamine are described. At room temperature with a strong base, t-BuXPhos is employed as the supporting ligand; at 110 °C with a weak base, XPhos is ...

Thiolane Sulfoximines as Azide Surrogates for Quinolyl Nitrenes: Photochemical Access to Ortho‐Diaminoquinolines

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Thiolane sulfoximines provide practical and safer surrogates for hazardous azides in nitrene photochemistry, enabling direct access to 7,8‐diaminoquinolines and fused δ‐lactams. DFT calculations support the reaction mechanism and rationalize product selectivity.

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...
