A Brønsted acid catalyzed redox arylation

Abstract

A Brønsted acid catalyzed redox arylation of ynamides that employs aryl sulfoxides as the arylating agents is reported. This metal-free transformation proceeds at room temperature and efficiently affords α-arylated oxazolidinones in a redox-neutral, atom-economic fashion.

Keywords: Brønsted acid catalysis; oxazolidinones; redox reactions; sulfoxides; ynamides.
