Iron(III) chloride mediated para-selective C−H chlorination and subsequent annulation of 2-amidophenol to synthesize C5- and C5, C7-chlorinated benzoxazoles was developed. Further, the oxidative cross-dehydrogenative coupling of amidophenol with anisole by ferricchloride was explored to achieve the remotely anisylated benzoxazoles.

An object is to provide a novel benzoxazole derivative. Another object is to reduce driving voltage of a light-emitting element. Still another object is to reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device. A benzoxazole derivative represented by General Formula (G1) is provided. The benzoxazole derivative represented by General Formula (G1) has an electron-injecting property and an electron-transporting property; accordingly, it can be favorably used for a light-emitting element, a light-emitting device, and an electronic device.

A RhIII‐catalysed three‐component synthesis of isoindolinone frameworks via direct assembly of benzoyl chlorides, o‐aminophenols and activated alkenes has been developed. The process involves in situ generation of o‐aminophenol (OAP)‐based bidentate directing group (DG), RhIII‐catalysed tandem ortho C−H olefination and subsequent cyclization via aza‐Michael addition. This protocol exhibits good chemoselectivity
A diversity-oriented synthesis of bioactive benzanilidesviaC(sp2)–H hydroxylation has been studied. The reaction demonstrates excellent regioselectivity, good tolerance of functional groups, and high yields.
