title: 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.
