evaluated as antifungal agents. A new and versatile synthesis of dithiins 1d and 1e is reported which is amenable to scale-up at the kilogram level. The novelty of the process derives from the use of beta-mercaptopropionitrile as the thiophile, relying on a beta-elimination strategy and subsequent oxidation to create the 1,2-dithiin ring. Optimal geometries of dithiins 1d, 18i, and 45 and model dithiin
本文报道了涉及1,2-二硫氨酸类化合物(1,2-二硫代环己二烯)的第一项结构活性研究。从双硫辛素1d和1e合成了一系列的3,6-二取代的1,2-二硫辛素,并作为抗真菌剂进行了评估。据报道,一种新的,多功能的二硫辛素1d和1e合成方法可以在千克水平上扩大规模。该方法的新颖性源于使用β-巯基丙腈作为亲硫试剂,它依赖于β-消除策略和随后的氧化作用以生成1,2-二硫辛环。通过分子力学和Hartree-Fock分子轨道计算确定了dithiins 1d,18i和45和模型dithiin 61的最佳几何形状。为1提供了两种可能的作用机制
