Rh-Catalyzed and Self-Directed Aromatic C–H Activation of Enaminones to Divergent Alkenylated and Annulated Compounds

Organic Letters, Год журнала: 2025, Номер unknown

Опубликована: Фев. 27, 2025

By means of simple Rh catalysis, the direct activation ortho-C-H bond in aryl enaminones has been realized with enaminone structure as a traceless directing fragment. The products resulting from C-H alkenylation and further annulation via intramolecular addition could be accessed depending upon alkenes. annulated used for easy synthesis valuable 2-aza-fluorenones one-pot operation by employing NH4OAc.

Oxidative Free-Radical C(sp²)–H Bond Chlorination of Enaminones with LiCl: Access to Highly Functionalized α-Chlorinated Enaminones

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(12), С. 8521 - 8530

Опубликована: Июнь 3, 2024

An oxidative free-radical C(sp2)–H bond chlorination strategy of enaminones has been developed by using LiCl as a chlorinating reagent and K2S2O8 an oxidant. This transformation provides new straightforward synthetic methodology to afford highly functionalized α-chlorinated with Z-configuration in good excellent yields.
