Compounds, compositions and methods for preventing, treating or curing a coronavirus, picornavirus, and/or Hepeviridae virus infection in human subjects or other animal hosts. Specific viruses that can be treated include enteroviruses. In one embodiment, the compounds can be used to treat an infection with a severe acute respiratory syndrome virus, such as human coronavirus 229E, SARS, MERS, SARS-CoV-1 (OC43), and SARS-CoV- 2. In another embodiment, the methods are used to treat a patient co-infected with two or more of these viruses, or a combination of one or more of these viruses and norovirus.
The photochemicalreaction of a series of 2-aryl-1,2-benzisothiazol-3(2H)-ones (1) under deaerated conditions was found to give dibenzo[b,f][1,4]thiazepin-11(10H)-ones (2). A mechanism through a biradical species is proposed for the photoreaction. When the photolysis of 1 was carried out in the presence of oxygen, 2-aryl-1,2-benzisothiazol-3(2H)-one 1-oxides (11) were formed together with compounds

Copper-catalyzed synthesis of benzo[d]isothiazol-3(2H)-ones and N-acyl-benzothiazetidine by intramolecular dehydrogenative cyclization is described. In this reaction, a new nitrogen–sulfur (N–S) bond is formed by N–H/S–H coupling. The present reaction has high functional group tolerance and gives products in gram scale. This method promotes double cyclization, allowing for synthesis of a drug intermediate
描述了铜通过分子内脱氢环化反应合成苯并[ d ]异噻唑-3(2 H)-酮和N-酰基-苯并噻唑烷的方法。在该反应中,通过NH / S-H偶联形成一个新的氮-硫(NS)键。本反应具有较高的官能团耐受性,并得到以克为单位的产物。该方法促进了双环化,从而允许合成药物中间体。
Phenyliodine(III) Bis(Trifluoroacetate) Mediated Synthesis of 2-Aryl-1,2-Benzisothiazol-3(2<i>H</i>)-Ones in Ionic Liquid
Treatment of N-aryl-2-(benzylthio)benzamides with phenyliodine(III) bis(trifluoroacetate) containing trifluoroacetic acid resulted in an interrupted Pummerer-type reaction in ionicliquid 1-n-butyl-3-methylimidazolium hexafluorophosphate, [bmim][PF 6 ] to give 2-aryl-1,2-benzisothiazol-3(2H)-ones rather than the normal Pummerer-type products.
Photoisomerization of the benzisothiazol-3(2H)-ones (1) gives the dibenzo[b,f][1,4]thiazepin-10(11H)-ones (4) Probably via homolytic cleavage of the S–N bond [(1)→(2)], cyclization of the biradical [(2)→(3)], followed by the formation of an aromatic ring together with 1,7-hydrogen transfer [(3)→(4)].
