A hepatoprotective experiment on taro vegetable (Colocasia esculenta (L.) Schott) flower employing animal models by mitigating oxidative stress

Animal Models and Experimental Medicine, EarlyView.
The antioxidant efficacy of Colocasia esculenta flower’s methanolic extract was assessed using 2,2′‐azino‐bis‐(3‐ethylbenzothiazoline‐6‐sulfonic) (ABTS) and 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) scavenging assay. The hepatoprotective effect was investigated by assessing liver injury indicators (amino transferase [ALT], aspartate amino transferase [AST],

Bidirectional cross metathesis and ring-closing metathesis/ring opening of a C2-symmetric building block: a strategy for the synthesis of decanolide natural products

Beilstein Journal of Organic Chemistry, 2013
Starting from the conveniently available ex-chiral pool building block (R,R)-hexa-1,5-diene-3,4-diol, the ten-membered ring lactones stagonolide E and curvulide A were synthesized using a bidirectional olefin-metathesis functionalization of the terminal ...

Ruthenium‐Katalysierte ortho‐Arylierung von Benzoesäuren mit Arylthianthreniumsalzen

Angewandte Chemie, EarlyView.
Es wurde eine katalytische Ortho‐Arylierungsmethode entwickelt, mit der Arylthianthreniumsalze in Carboxylat‐funktionalisierte Biaryle umgewandelt werden können. Die Carboxylatgruppe kann in situ entfernt oder für eine weitere Derivatisierung verwendet werden.
