Qige Decoction attenuated non-alcoholic fatty liver disease through regulating SIRT6-PPARα-mediated fatty acid oxidation.

Background: Sirtuin 6 (SIRT6), a potential therapeutic target for non-alcoholic fatty liver disease (NAFLD), has been shown to regulate fatty acid oxidation (FAO) by interacting with peroxisome proliferator-activated receptor α (PPARα). However, the impact of SIRT6-PPARα pathway on NAFLD phenotype has not yet been reported. Qige decoction (QG), a traditional Chinese medicine (TCM) formula, is widely applied to treat disorders of glycolipid metabolism.

Constructing an Isopolymolybdate-Based Bifunctional Photocatalyst for Promoting Nitroaromatic Reduction and C-H Oxidation.

Amide compounds are widely present in drug molecules and natural products, which can be synthesized by acid-amine condensation.

A general copper-catalysed enantioconvergent C(sp)-S cross-coupling via biomimetic radical homolytic substitution.

Although α-chiral C(sp)-S bonds are of enormous importance in organic synthesis and related areas, the transition-metal-catalysed enantioselective C(sp)-S bond construction still represents an underdeveloped domain probably due to the difficult heterolytic metal-sulfur bond cleavage and notorious catalyst-poisoning capability of sulfur nucleophiles. Here we demonstrate the use of chiral tridentate anionic ligands in combination with Cu(I) catalysts to enable a biomimetic enantioconvergent radical C(sp)-S cross-coupling reaction of both racemic secondary and tertiary alkyl halides with highly transformable sulfur nucleophiles. This protocol not only exhibits a broad substrate scope with high enantioselectivity but also provides universal access to a range of useful α-chiral alkyl organosulfur compounds with different sulfur oxidation states, thus providing a complementary approach to known asymmetric C(sp)-S bond formation methods.

Design of Hemilabile N,N,N-Ligands in Copper-Catalyzed Enantioconvergent Radical Cross-Coupling of Benzyl/Propargyl Halides with Alkenylboronate Esters.

The enantioconvergent radical C(sp)-C(sp) cross-coupling of alkyl halides with alkenylboronate esters is an appealing tool in the assembly of synthetically valuable enantioenriched alkenes owing to the ready availability, low toxicity, and air/moisture stability of alkenylboronate esters. Here, we report a copper/chiral N,N,N-ligand catalytic system for the enantioconvergent cross-coupling of benzyl/propargyl halides with alkenylboronate esters (>80 examples) with good functional group tolerance. The key to the success is the rational design of hemilabile N,N,N-ligands by mounting steric hindrance at the ortho position of one coordinating quinoline ring.

Copper-Catalyzed Intermolecular Enantioselective Radical Oxidative C(sp )-H/C(sp)-H Cross-Coupling with Rationally Designed Oxazoline-Derived N,N,P(O)-Ligands.

The intermolecular asymmetric radical oxidative C(sp )-C(sp) cross-coupling of C(sp )-H bonds with readily available terminal alkynes is a promising method to forge chiral C(sp )-C(sp) bonds because of the high atom and step economy, but remains underexplored. Here, we report a copper-catalyzed asymmetric C(sp )-C(sp) cross-coupling of (hetero)benzylic and (cyclic)allylic C-H bonds with terminal alkynes that occurs with high to excellent enantioselectivity. Critical to the success is the rational design of chiral oxazoline-derived N,N,P(O)-ligands that not only tolerate the strong oxidative conditions which are requisite for intermolecular hydrogen atom abstraction (HAA) processes but also induce the challenging enantiocontrol.
