1,3-Thiazines, XVI: 2-Thioxotetrahydro-1,3-thiazin-4-ones by Use of β-Propiolactones, Part 2

Reactions of β-lactones with dithiocarbamates leading to 2 and cyclization of the products yielding 2-thioxo-tetrahydro-1,3-thiazin-4-ones 3 are described.With derivatives of diketene (β-propiolactones with exocyclic double bonds) no 1,3-thiazines 6 are obtained.Instead, the amides of β-ketoacids 7 are formed with the elimination of carbon disulfide.
