The saccharine nucleus has long been recognized as a significant component in medicine. A series of pseudo-saccharine amines derivatives (7a-j) were synthesized and examined for their antibacterial activity. After testing all compounds, 7b, 7f, 7g, 7i and 7j were found most effective against Escherichia coli, Streptococcus aureus and Bacillus subtilis strains. The MIC of the compound was found from 4.6 to 16.1 μM. Further, compound 7f and 7i exhibited excellent activity against E.coli and Bacillus subtilis with MIC value 4.6 and 4.7 μM respectively. The compound 7b and 7i was found active against all the three bacteria. The zone inhibition was observed at 10 μM against Escherichia coli, Staphylococcus aureus and Bacillus subtilis at 0.9, 1.8, 3.9 respectively for 7b and 1.0, 1.8 and 2.0 cm respectively for 7i.

Paragraph 0033-0076; 0081-0090, (2020/07/02)
1,2 - Benzisothiazol -3 - ketone compounds are subjected to an oxidation reaction with an oxidizing agent, and an oxidizing agent oxidizes thioether of 1,2 - benzisothiazol -3 -one compound to thioamide to obtain the O-benzoyl sulfamide compound. Compared with the traditional production technology of saccharin, the saccharin synthesis method has the advantages of simple process, low cost, high separation efficiency, low pollution and the like, and accords with the green chemistry.
