The nucleophilic addition of widely available and variously functionalized organolithium reagents to isothiocyanates represents a straightforward, high‐yielding, one‐pot method to access secondary thioamides. The simple reaction conditions required and the broad scope (>50 cases examples) makes it a robust and reliable method to access both simple and complex thioamides, including enantiopure ones
在异硫氰酸酯中亲和性广泛获得的各种官能化有机锂试剂的亲核加成反应是直接,高产率,一锅法获得仲硫代酰胺的方法。所需的简单反应条件和广泛的应用范围(> 50个案例)使其成为一种既简便又复杂的硫酰胺类(包括对映纯类)的可靠可靠的检测方法。在整个合成过程中避免使用通常在文献确定的方法中使用的有毒和难闻的硫化剂,从而使该方案在可持续性方面也具有很高的吸引力。
