Copper‐Catalyzed Aza‐Sonogashira Cross‐Coupling to Ynimines: Development and Application to the Synthesis of Heterocycles

Jieping Zhu, Rémi Hugo Lavernhe, Qiang Wang

Nitrogen substituted alkynes such as ynamines and ynamides are versatile synthetic building blocks in organic chemistry. Ynimines bearing additional nucleophilic and electrophilic centers relative to ynamines and ynamides are expected to have high syntheti ...

Local structural investigation of hafnia-zirconia polymorphs in powders and thin films by X-ray absorption spectroscopy

Reinis Ignatans

Despite increasing attention for the recently found ferro- and antiferroelectric properties, the polymorphism in hafnia- and zirconia-based thin films is still not sufficiently understood. In the present work, we show that it is important to have a good qu ...

Dopaminergic modulation of motor network compensatory mechanisms in Parkinson's disease

Michael Herzog, Bogdan Draganski, Maya Anna Jastrzebowska, Renaud Marquis

The dopaminergic system has a unique gating function in the initiation and execution of movements. When the interhemispheric imbalance of dopamine inherent to the healthy brain is disrupted, as in Parkinson's disease (PD), compensatory mechanisms act to st ...
