Dietary phenolics: chemistry, bioavailability and effects on health.

Glacial melting in the Tibetan Plateau affects the water resources of millions of people. This study finds that—partly owing to changes in atmospheric circulations and precipitation patterns—the most intensive glacier shrinkage is in the Himalayan region, whereas glacial retreat in the Pamir Plateau region is less apparent.

Different glacier status with atmospheric circulations in Tibetan Plateau and surroundings

Transition-Metal-Catalyzed C−S, C−Se, and C−Te Bond Formation via Cross-Coupling and Atom-Economic Addition Reactions

The invention relates to new application of 6'-O-caffeoyl-arbutin in the technical field of medicines for inhibiting melanin, particularly application of 6'-O-caffeoyl-arbutin or derivatives thereof, or a natural, synthetic or semisynthetic mixture containing the 6'-O-caffeoyl-arbutin, or a composition containing the 6'-O-caffeoyl-arbutin in preparing cosmetics for whitening skin and removing freckles or medicines for whitening skin and treating chromatodermatosis The 6'-O-caffeoyl-arbutin can effectively inhibit and decompose melanin, thoroughly remove the melanin freckles, and have the effect of whitening skin and removing freckles; and the zebra fish acute toxicity test indicates that compared with arbutin, the 6'-O-caffeoyl-arbutin has the characteristics of lower toxicity, higher activity, higher efficiency and higher safety

New anti-HBV sesquiterpene glycosides and amino acid–sesquiterpene conjugates from the roots of Saussurea lappa

Three new diterpenoids - phyllanflexoids A-C (I), (II), and (III) - are isolated from roots of Phyllanthus flexuosus.

Phyllanflexoid C: First Example of Phenylacetylene-Bearing 18-Nor-Diterpenoid Glycoside from the Roots of Phyllanthus flexuosus.

The highly enantioselective construction of a quaternary carbon center of dihydroquinazoline by an asymmetric Mannich reaction and chiral recognition are described. The key transformation was to establish the chiral trifluoromethyl quaternary carbon center by a diamine-Bronsted acid-catalyzed enantioselective and regioselective Mannich reaction of a methyl ketone and 4-trifluoromethyldihydroquinazoline. An unusual phenomenon of self-discrimination of enantiomers in hydrogen-bonded dimers was observed. A valuable intermediate was transformed into the enantiopure HIV reverse transcriptase inhibitor DPC 083 (>99.9 ee) simply by reduction of the carbonyl group and elimination of the hydroxy group in hexamethylphosphoric tramide (HMPA).
