Atmospheric aerosols play an important role in climate by scattering and absorbing radiation and by serving as cloud condensation nuclei. An aerosol's optical or nucleation properties are driven by its chemical composition. Chemical aging of aerosols by atmospheric oxidants,...

BACKGROUND: Low serum albumin is common and associated with protein-energy wasting, inflammation, and poor outcomes in maintenance hemodialysis (MHD) patients. We hypothesized that in-center (in dialysis clinic) provision of high-protein oral nutrition supplements (ONS) tailored for MHD patients combined...

We report the first examples of Au(III) tricationic complexes bound only by neutral monodentate ligands, which are a new class of gold reagents. Oxidative addition to the bis-pyridine Au(I) cation, [Au(4-DMAP)2](+), using a series of dicationic I(III) oxidants of...

O-Acyl oximes: versatile building blocks for N-heterocycle formation in recent transition metal catalysis.

Organic & biomolecular chemistry

Huang H, Cai J, Deng GJ.
PMID: 26727109
Org Biomol Chem. 2016 Feb 07;14(5):1519-30. doi: 10.1039/c5ob02417j.

O-Acyl oximes are versatile building blocks being widely applied in organic synthesis, especially for N-heterocycle construction under transition metal catalysis. In the last decade, aza-Heck cyclization using oximes has been progressing in the preparation of functionalized pyrrolines, and instead...
