Ring‐Fused 1,2‐Dithioles, III. – Synthesis of 1,2‐Dithiolo‐furans A series of 1,3‐dithiino‐furans 4/9 has been synthesized by starting with the β‐ketoester 5a or the cyclic ketone 5b. The dithiines undergo oxidative ring contraction to give the corresponding 1,2‐dithiolo‐furans 3/14. The ester func
