Direct Photoredox-Catalyzed Reductive Difluoromethylation of Electron-Deficient Alkenes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Tang XJ, Zhang Z, Dolbier WR.
PMID: 26527168
Chemistry. 2015 Dec 21;21(52):18961-5. doi: 10.1002/chem.201504363. Epub 2015 Nov 17.

Photoredox-catalyzed reductive difluoromethylation of electron-deficient alkenes was achieved in one step under tin-free, mild and neutral conditions. This protocol affords a facile method to introduce RCF2 (R=H, Ph, Me, and CH2N3) groups at sites β to electron-withdrawing groups. It...

From Biomass-Derived Furans to Aromatics with Ethanol over Zeolite.

Angewandte Chemie (International ed. in English)

Teixeira IF, Lo BT, Kostetskyy P, Stamatakis M, Ye L, Tang CC, Mpourmpakis G, Tsang SC.
PMID: 27490584
Angew Chem Int Ed Engl. 2016 Oct 10;55(42):13061-13066. doi: 10.1002/anie.201604108.

We report a novel catalytic conversion of biomass-derived furans and alcohols to aromatics over zeolite catalysts. Aromatics are formed via Diels-Alder cycloaddition with ethylene, which is produced in situ from ethanol dehydration. The use of liquid ethanol instead of...

Recent Progress in Stem Cell Therapy for Diabetic Nephropathy.

Kidney diseases (Basel, Switzerland)

Liu Y, Tang SC.
PMID: 27536688
Kidney Dis (Basel). 2016 Apr;2(1):20-7. doi: 10.1159/000441913. Epub 2015 Dec 05.

BACKGROUND: Diabetic nephropathy (DN) represents the leading cause of end-stage renal disease. Current therapeutic strategies for DN are very limited, and none of them can stop end-stage renal disease progression. Stem cell-based therapy showed encouraging outcomes in kidney disease,...

Strategy for the Realization of Efficient Solution-Processable Phosphorescent Organic Light-Emitting Devices: Design and Synthesis of Bipolar Alkynylplatinum(II) Complexes.

Journal of the American Chemical Society

A new class of highly luminescent bipolar alkynylplatinum(II) complexes has been synthesized, characterized, and applied as phosphorescent dopants in the fabrication of solution-processable organic light-emitting devices (OLEDs). Through the incorporation of a delicate balance of electron-donating carbazole moieties and...

Neutrons produced by the carbon fusion reaction (12)C((12)C,n)(23)Mg play an important role in stellar nucleosynthesis. However, past studies have shown large discrepancies between experimental data and theory, leading to an uncertain cross section extrapolation at astrophysical energies. We present...

Chiral phosphoric acid catalyzed enantioselective decarboxylative alkylation of β-keto acids with 3-hydroxy-3-indolyloxindoles.

Organic letters

Tang XD, Li S, Guo R, Nie J, Ma JA.

Org Lett. 2015 Mar 20;17(6):1389-92. doi: 10.1021/acs.orglett.5b00159. Epub 2015 Mar 02.

A chiral phosphoric acid catalyzed enantioselective decarboxylative alkylation of β-keto acids with 3-hydroxy-3-indolyloxindoles is described in this context. This method tolerates a series of aromatic and aliphatic β-keto acids as well as substituted 3-hydroxy-3-indolyloxindoles, affording the corresponding chiral 3-functionalized...

Recent advances in managing and understanding diabetic nephropathy.

F1000Res. 2016 May 31;5. doi: 10.12688/f1000research.7693.1. eCollection 2016.

Diabetic nephropathy is the commonest cause of end-stage renal disease in most developed economies. Current standard of care for diabetic nephropathy embraces stringent blood pressure control via blockade of the renin-angiotensin-aldosterone system and glycemia control. Recent understanding of the...

Muscle-based biohybrid actuators have generated significant interest as the future of biorobotics but so far they move without having much control over their actuation behavior. Integration of microelectrodes into the backbone of these systems may enable guidance during their...

PMID: 25837062
Opt Express. 2015 Mar 23;23(6):7173-83. doi: 10.1364/OE.23.007173.

A system framework is proposed and analyzed for generating polarization-resolved wideband unpredictability-enhanced chaotic signals based on a slave vertical-cavity surface-emitting laser (S-VCSEL) driven by an injected optical chaos signal from a master VCSEL (M-VCSEL) under optical feedback. After calculating...
