Palladium-catalyzed selective activation of allyl alcohols as allyl cations, allyl anions, and zwitterionic trimethylenemethanes [PDF]
Pd-Et3B catalytic system promotes the generation of allyl cations, allyl anions, and zwitterionic trimethylenemethane species from the corresponding allylic alcohols. Allyl cations react with a wide variety of nucleophiles, e.g., amines, active methylene

Phospholipase D in Phytophthora infestans and Its Role in Zoospore Encystment
We show that differentiation of zoospores of the late blight pathogen Phytophthora infestans into cysts, a process called encystment, was triggered by both phosphatidic acid (PA) and the G-protein activator mastoparan. Mastoparan induced the accumulation

CO2/H2-mediated toluene methylation over metal oxide–zeolite bifunctional catalyst offers a sustainable route for para-xylene (PX) synthesis, yet how zeolite morphology and acidity synergistically govern this coupled process remains unclear.

Carboxylic acids, as a fundamental raw material, are widely used in the production of fine chemicals. Herein, we developed the oxidation of alcohols to carboxylic acids under visible light irradiation at room temperature by devising a duplex NH2-MIL-125 ...

Palladium-Catalyzed Allylation/Benzylation of H-Phosphinate Esters with Alcohols
The Pd-catalyzed direct alkylation of H-phosphinic acids and hypophosphorous acid with allylic/benzylic alcohols has been described previously. Here, the extension of this methodology to H-phosphinate esters is presented. The new reaction appears general,

Abstract There is evidence for a dose-response relationship between alcohol consumption and risk of liver cirrhosis, cancers of the oropharynx, larynx, oesophagus, rectum (beer only), liver, and female breast, and violent death, but the relationship between alcohol consumption and cardiovascular disease is more complex.

Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
