A new mode for the activation of elemental sulfur is reported. In the presence of both DMSO and a tertiary aliphatic amine (triethylamine or N-methylpiperidine), this element reacts directly with a wide range of 2′-nitrochalcones 1 to provide the corresponding thioaurones 2 in high yields even at room temperature and in the absence of transition metal catalyst.

A rapid, one-step preparation of 2-(arylmethylidene)-1-benzothiophen-3-ones (thioaurones) using directed α-metallation, ring closure and aldol-type condensation is described. The reaction leads exclusively to the Z-isomer.
