operationally simple and user-friendly process to access privileged scaffolds such as acids, amides and isothiazoles has been devised employing β-ketodithioesters for the first time. Remarkably, the new protocol involves combination of CC bond cleavage and CO/CN/NS bond formations in one-pot. Aqueousammonia led to the formation of skeletally distinct amide and isothiazole, whereas aqueous NaOH enabled
首次设计了一种使用β-酮二硫酯的操作简单且用户友好的方法,可访问特权支架,例如酸,酰胺和异噻唑。值得注意的是,新方案涉及一锅中C C键断裂和C O / C N / N S键形成的组合。氨水导致骨骼上截然不同的酰胺和异噻唑的形成,而NaOH水溶液则使芳香酸的形成接近定量产率。这种实用的方法可以极大地简化简单分子的合成,具有高度的化学选择性,成本效益,可克量级,对水分不敏感以及具有很高的官能团相容性。
