European Journal of Organic Chemistry, EarlyView.Palladium(II)‐catalyzed intramolecular C─H alkenylation of cinnamides allows the atroposelective synthesis of axially chiral 4‐arylquinolones, with the chirality being installed by ring formation. DFT studies have shown that the reaction proceeds by prior activation of the alkene and the enantioselectivity is determined during the β‐hydride elimination

Iridium Catalyzed Asymmetric Hydrogenation of 5‐Methylene‐Benzosuberanes
European Journal of Organic Chemistry, EarlyView.Asymmetric hydrogenation of 5‐methylene‐benzosuberanes using Ir‐PHOX catalysts is reported. Investigation of catalyst structure–activity relationships drove the design of Ir–NoaPHOX, a novel catalyst engineered to suppress an undesired isomerization pathway. This catalyst eliminated pressure‐dependent selectivity, allowing efficient hydrogenation under

Mo‐Catalyzed Synthesis of 3‐Substituted Quinolines From Nitroarenes and Aldehydes
European Journal of Organic Chemistry, EarlyView.A one‐pot Friedländer synthesis of 3‐substituted quinolines from readily available o‐nitrobenzaldehydes and aldehydes or acetals has been developed under dioxomolybdenum(VI) catalysis. Pinacol acts as a benign reductant, enabling in situ nitroarene reduction and annulation without isolation of o‐aminobenzaldehydes and provides access to diverse ...

Support and destigmatization in early pregnancy loss in Spain
Feminist Anthropology, EarlyView.Abstract Early miscarriages are a frequent reproductive event, often silenced and shrouded in stigma. Feminist anthropology has pointed out how such losses challenge the widespread Euro‐American social representations of motherhood and pregnancy, as well as societal unease with death.
