Manufacture of 3-halosulfonylthiophene-carboxylic acid compounds

3-Halosulfonylthiophene-carboxylic acid compounds are manufactured by reacting 3-ketothiophane-carboxylic acid compounds with sulfonic acid compounds, reacting the end product from the 1st reaction stage with alkali metal polysulfides, reacting the end product from the 2nd stage with a dehydrogenating agent and finally reacting the end product from the 3rd stage with halogen and water. The products are starting compounds for the manufacture of drugs, dyes and crop protection agents and have an anti-inflammatory, analgesic and anti-rheumatic action. In particular, the end products I are starting materials for the manufacture of sweeteners which are non-toxic and free from an after-taste, flavor-improving agents, diabetic aids and feedstuffs, and provide the means of a simple and economical synthesis of thiophene-saccharins.

Thiophene saccharines

Thiophene analogs of saccharine, i.e., the new compounds 2,3-dihydro-3-oxothieno-[3,4-d]-, -[2,3-d]- and -[3,2-d]-isothiazole-1,1-dioxide, and processes for their manufacture. The new compounds are excellent sweeteners and have no unpleasant taste.
