We report a catalytic, light-driven method for the intramolecular hydroetherification of unactivated alkenols to furnish cyclic ether products. These reactions occur under visible-light irradiation in the presence of an IrIII-based photoredox catalyst, a Br?nsted base catalyst, and a hydrogen-atom transfer (HAT) co-catalyst. Reactive alkoxy radicals are proposed as key intermediates, generated by direct homolytic activation of alcohol O?H bonds through a proton-coupled electron-transfer mechanism. This method exhibits a broad substrate scope and high functional-group tolerance, and it accommodates a diverse range of alkene substitution patterns. Results demonstrating the extension of this catalytic system to carboetherification reactions are also presented.

A novel series of hydrazide derivatives were synthesized as potential diacylglycerol acyltransferase (DGAT) inhibitors. Among them, compounds 8u and 8v exhibited selective and potent DGAT-1 inhibitory activities. In addition, compound 8u dose-dependently inhibited triglyceride synthesis in HepG2 cell lines. Furthermore, treatment with compound 8u for an oral lipid tolerance test showed a significant decrease in plasma triglyceride levels compared with vehicle-treated control animals, indicating delayed absorption of triglyceride after an acute lipid challenge.
