Ring-Fused 1,2-Dithioles, II. - Synthesis of Thieno-1,2-dithiolesA series of thieno-1,3-dithiines 5 has been synthesized starting with the β-thioxoester 4. The dithiines undergo oxidative ring contraction to the corresponding thieno-1,2-dithioles 6. Analogously, the dithiolo-dithiines 8 form the 1,2-dithiolo-1,2-dithioles (1,2,4,5-tetrathiapentalenes) 14 by ring contraction. - The ester function of 6f is easily removed to give 2, the thioanalog of the antibiotic thiolutine.
