People with type 2 diabetes (T2D) have a greater risk of developing neurodegenerative diseases, like Alzheimer's disease, in later life. Exogenous ketone supplements containing the ketone body β-hydroxybutyrate (β-OHB) may be a strategy to protect the brain as β-OHB can support cerebral metabolism and promote neuronal plasticity via expression of brain-derived neurotrophic factor (BDNF). Parallel human (ClinicalTrials.

A one-pot methodology for the tandem acylation and oxidative aromatization of vinylogous thioesters to 2-acyl-5-(alkyl/arylthio)phenols is presented. Initially, cyclohexane-1,3-diones were converted to vinylogous thioesters through FeCl3-mediated thioenolization. This was followed by LiTMP-mediated acylation and DDQ-mediated aromatization, which resulted in the synthesis of sulphur derived oxybenzone analogs.
