The novel 2-thioxohydantoin ketene S,S-acetals 3a,b were prepared by the reaction of 2-thioxohydantoins 1a,b with carbon disulfide, followed by alkylation with methyl iodide of the produced sodium dithiolate salts 2a,b. The reaction of compounds 3a,b with nucleophiles afforded different fused methylsulfanylimidazoles.
