A representative procedure for synthesis of thioaurones is as follows. To a solution of 150 nig (1.00 mmol) of 1-thiobenzofuranone and the required aldehyde (1 mmol) in 2 mL of methanol was added 2 mL of a 50% by weight solution of potassium hydroxide in methanol. This mixture was heated to 60 C in a CEM microwave reactor for 30 minutes. After cooling, the reaction was acidified with 1-N HC1 and partitioned between ethyl acetate and water. The organic layer was directly concentrated in vacuo and then purified via column chromatography on silica using ethyl acetate/hexanes mixtures to afford the desired thioaurone product as a solid in 20-50% yield.

To a 5 mL flame-dried microwave flask was added benzo[b]thiophen-3(2H)-one (0.24 mmol, 0.12 equiv) and 5-aryl-2-formylpyrrole (0.2 mmol, 0.1 equiv). The flask was capped with analuminume-PTFE crimp cap, sealed, and evacuated and backfilled with nitrogen three times. To the flask was then added anhydrous toluene (2 mL, 0.1M in aldehyde) and piperidine (10 mL, 0.1 mmol,0.5 equiv). The flask was transferred to a pre-warmed oil bath set to 111 C and stirred for 2 h. After 2 h the flask was removed from theoil bath and cooled to room temperature and then to 0 C in a water-ice bath. To the flask was added hexanes (5 mL) and the flask was allowed to sit for an addition 10-30 min. The mixture was the filtered, and the precipitate was then triturated with hexanes to until the filtrate ran clear to provide the pure product as a red, blue,or purple solid depending on the substrate.
