B(C6F5)3‐Catalyzed Regioselective Ring Opening of Cyclic Amines with Hydrosilanes

open access: yesChemistry – A European Journal, Volume 29, Issue 13, March 1, 2023., 2023
The strong boron Lewis acid B(C6F5)3 in combination with phenylsilane enables the regioselective cleavage of one out of two or three carbon–nitrogen bonds in cyclic secondary and tertiary amines, respectively. This amine deconstruction extends to large saturated nitrogen‐containing heterocycles, and the functional‐group tolerance is good.

Higenamine alleviates cerebral ischemia-reperfusion injury in rats

open access: yesFrontiers in Bioscience, 2019
Cerebral ischemia reperfusion (I/R) injury is associated with a high incidence of neurological morbidity and mortality worldwide. Higenamine has anti-inflammatory, anti-oxidative and anti-apoptotic capacities and has been successfully used in myocardial and intestinal ischemia reperfusion. We hypothesized that higenamine might serve the same effects in
