Oxidative Asymmetric [2 + 3] Annulation of Aldehydes with Azomethine Imines Enabled by N-Heterocyclic Carbene Catalysis

02-Nov-2017 | Shiru Yuan; Yuchen Luo; Jingyi Peng; Maozhong Miao; Jianfeng Xu; Hongjun Ren, Organic Letters, 2017

An efficient asymmetric [2 + 3] annulation of simple aldehydes with N,N′-cyclic azomethine imines via oxidative N-heterocyclic carbene (NHC) catalysis is disclosed, affording bicyclic pyrazolidinones bearing two vicinal tertiary stereogenic centers with moderate to good yields (56–84% for 19 ...

Kinetic Insights into Hydrogen Sulfide Delivery from Caged-Carbonyl Sulfide Isomeric Donor Platforms

02-Nov-2017 | Yu Zhao; Hillary A. Henthorn; Michael D. Pluth, Journal of the American Chemical Society, 2017

Hydrogen sulfide (H2S) is a biologically important small gaseous molecule that exhibits promising protective effects against a variety of physiological and pathological processes. To investigate the expanding roles of H2S in biology, researchers often use H2S donors to mimic enzymatic H2S ...

In Vivo Biochemistry: Single-Cell Dynamics of Cyclic Di-GMP in Escherichia coli in Response to Zinc Overload

02-Nov-2017 | Jongchan Yeo; Andrew B. Dippel; Xin C. Wang; Ming C. Hammond, Biochemistry, 2017

Intracellular signaling enzymes drive critical changes in cellular physiology and gene expression, but their endogenous activities in vivo remain highly challenging to study in real time and for individual cells. Here we show that flow cytometry can be performed in complex media to monitor ...

Switchable Surfactants for the Preparation of Monodisperse, Supported Nanoparticle Catalysts

01-Nov-2017 | Kristin Bryant; Gasim Ibrahim; Steven R. Saunders, Langmuir, 2017

Synthesis methods for the preparation of monodisperse, supported nanoparticles remain problematic. Traditional synthesis methods require calcination following nanoparticle deposition to remove bound ligands and expose catalytic active sites. Calcination leads to significant and unpredictable ...

Excited-State Proton Transfer on the Surface of a Therapeutic Protein, Protamine

01-Nov-2017 | Ankur A. Awasthi; Prabhat K. Singh, The Journal of Physical Chemistry B, 2017

Proton transfer reactions on biosurfaces play an important role in a myriad of biological processes. Herein, the excited-state proton transfer reaction of 8-hydroxypyrene-1,3,6-trisulfonate (HPTS) has been investigated in the presence of an important therapeutic protein, Protamine (PrS), using ...
