this paper, we report a new process for the construction of 3,4,5-substituted isothiazoles via reaction cascades including Pummerer-like rearrangement, nucleophilic condensation, and sulfenamide cyclization followed by concomitant elimination and dehydration under mild reaction conditions. This process provides isothiazoles bearing fluorine and other functional groups in good to excellent yields from
在本文中,我们报道了一种通过反应级联构建 3,4,5-取代异噻唑的新工艺,包括类似 Pummerer 的重排、亲核缩合和次磺酰胺环化,然后在温和的反应条件下伴随消除和脱水。该方法从容易获得的起始材料中以良好至极好的收率提供带有氟和其他官能团的异噻唑。
