Pocahemiketone A, a Sesquiterpenoid Possessing a Spirocyclic Skeleton with a Hemiketal Endoperoxide Unit, Alleviates
Abstract:
Pocahemiketone A, a novel sesquiterpenoid possessing a unique spirocyclic skeleton with a hemiketal endoperoxide unit, was isolated from the essential oil of Pogostemon cablin. Its structure was determined by spectroscopic methods and single-crystal X-ray diffraction analyses. Pocahemiketone A exhibits a significant neuroprotective effect against Aβ25-35-induced damage in SH-SY5Y cells by inhibiting NLRP3 inflammasome-mediated pyroptosis and oxidative stress. These results indicate that pocahemiketone A has great potential for use in the treatment of Alzheimer's disease.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
