Mechanistic Study on the Palladium(II)-Catalyzed Synthesis of 2,3-Disubstituted Indoles Under Aerobic Conditions: Anion Effects and the Development of a Low-Catalyst-Loading Process

Jieping Zhu, Qian Wang, Bo Yao

As a result of detailed mechanistic and kinetic studies, we have proposed that PdX2-catalyzed oxidative coupling of o-alkynylanilines 1 with terminal alkynes 2 under aerobic conditions is initiated by aminopalladation of 1 followed by ligand exchange of th ...

Automated transfer and injection of hyperpolarized molecules with polarization measurement prior to in vivo NMR

Arnaud Comment, Josefina Adriana Maria Bastiaansen, Tian Cheng, Mor-Miri Mishkovsky

Hyperpolarized magnetic resonance via dissolution dynamic nuclear polarization necessitates the transfer of the hyperpolarized molecules from the polarizer to the imager prior to in vivo measurements. This process leads to unavoidable losses in nuclear pol ...

Copper-Catalyzed Tyrosine Nitration

Hubert Girault, Liang Qiao, Yu Lu

Tyrosine nitration, often observed during neurodegenerative disorders under nitrative stress, is usually considered to be induced chemically either by nitric oxide and oxygen forming nitrogen dioxide or by the decomposition of peroxynitrite. It can also be ...
