Platinum-Catalyzed Michael Addition and Cyclization of Tertiary Amines with Nitroolefins by Dehydrogenation of α,β-sp³ C−H Bonds Dahkki Xiao-Feng Xia (1393102)

“…A mild platinum-catalyzed oxidative dehydrogenation of α,β-C(sp³)−H bonds of tertiary amines in the presence of ambient oxygen is revealed, and the in situ formed enamines subsequently reacting with various nitroolefins resulted in the development of two one-pot synthetic protocols involving Michael addition−elimination and Michael addition−cyclization. …”

1,4-Hydroboration Reactions of Electron-Poor Aromatic Rings by N‑Heterocyclic Carbene Boranes Dahkki Wen Dai (1607932)

“…When regioisomers are possible, the more crowded (doubly ortho-substituted) product is formed preferably or exclusively. The mechanism may involve oxidation of the NHC-borane to an NHC-boryl radical, reduction of the electron-poor aromatic ring to a radical anion, coupling of the radical and the radical anion to give a cyclohexadienyl anion, and finally regioselective protonation.…”

Hepatic neuroendocrine neoplasm: imaging patterns Dahkki Abdallah de Paula Houat (10379710)

“…However, primary hepatic involvement is quite rare. Hepatic NENs can have a variety of radiological presentation forms and can therefore mimic other lesions, making their diagnosis challenging. …”

Congenital Zika syndrome and neuroimaging findings: what do we know so far? Dahkki Bruno Niemeyer de Freitas Ribeiro (4647952)

“…<div><p>Abstract Although infection with the Zika virus was first recognized in 1942, it received little attention until 2007, when a true pandemic spread throughout Africa, Asia, and the Americas. Since then, numerous forms of central nervous system involvement have been described, mainly malformations related to congenital infection. …”
