practical method for the straightforward construction of unsymmetrical selenoureas and cycloselenoureas via the combination of selenium powder, chloroform, and two different amines was comprehensively achieved in one-pot with only the assistance of a base under mild conditions. Thirty-three new structures of unsymmetrical selenoureas including three chiral examples and eight cycloselenoureas were achieved
仅通过在温和条件下的碱的辅助下,在一锅中全面实现了通过硒粉,氯仿和两种不同的胺的组合直接构建不对称硒脲和环硒脲的有效方法。获得了不对称硒脲的33个新结构,包括三个手性实例和八个环硒脲。实际上,通过该方案以克为单位合成了具有良好杀真菌活性的1,1-二甲基-3-苯基硒代脲II。对照实验进一步证实了异芥子氰酸酯为关键中间体。
