Efficient Synthesis of Benzothiazolone Derivatives by a Domino Reaction of Disulfide and COS under Mild Conditions

Carbonyl sulfide (COS), whose molecular structure is similar to CO2 and CS2, could be used as a better alternative carbonyl reagent due to its high chemical activity. However, the unfriendly by-product H2S would be generated when COS is used as a carbonyl reagent in the carbonylation reaction. In this report, the odorless and stable disulfide was used to replace the traditional foul smelling and unstable o-aminobenzenethiol to react with COS for preparing benzothiazolone derivatives in excellent yield, in which coupling reaction of H2S generation and S–S bond cleavage was firstly designed. Notably, the C=O of COS was converted into benzothiazolone derivatives by carbonylation reaction and the sulfur of COS was transformed into sulfur and sulfide after cleaving the S–S bond by a domino reaction of disulfide and COS under mild conditions. This efficient synthetic methodology provided a promising process for the utilization of COS.

6-Sulfonylbenzothiazolones as potential scaffolds for the design of 5-HT6 ligands

5-HT6 Receptors are relatively recently discovered receptors that interact with cholinergic, glutamatergic, GABAergic and dopaminergic transmission systems. These receptors have been implicated in the CNS system as therapeutic targets in applications such as psychosis, reduction of body weight or Alzheimer's disease. As part of our efforts to develop 5-HT6 antagonists, we explored the benzothiazolone scaffold substituted in position 3 or 6 respectively with ethylamino chains and an aromatic ring connected through a sulfonyl linker. Final compounds were evaluated in radioligand binding assays for their ability to interact with 5-HT6 receptors. Their potential cytotoxic effects were determined on the human neuroblastoma cell line SY5Y. They showed very low cytotoxicity, and one of them has submicromolar affinity for 5-HT6 receptors.

Copper catalyzed three-component synthesis of benzothiazolones from o-iodoanilines, DMF, and potassium sulfide

A copper catalyzed three-component reaction was developed for the synthesis of benzothiazolones. In the presence of CuBr2, the reaction of o-iodoanilines and K2S with DMF proceeded smoothly and generated the corresponding benzothiazolones with good isolated yields. DMF functioned both as the carbon monoxide source and as the reaction medium in this reaction.
