## Abstract Reaction of 3‐bromo‐3‐methylbutan‐2‐one (1) with mercapto‐esters 2 affords 5‐oxo‐3‐thiahexanoates 3 which cyclize to thiane‐3,5‐diones 4. Conversion of these dicarbonyl compounds to their ethyl enol ethers 5–7 followed by reduction with LiAlH~4~ gives 2__H__,6__H__‐thiin‐3‐ones 8–10. On
