transformation generates two C–C bonds in a single operation and presumably proceeds through a reaction sequence comprising 2-mercaptoacetaldehyde generation, nucleophilic carbonyl addition, annelation and elimination steps.
Keywords: C–C bond generation; nitroarenes; nitroketeneacetals; sulfur heterocycles
