design and synthesis of stable 1,2-dithietane derivatives for the generation of diatomicsulfur (S 2 ) was undertaken. Computer-aided evaluation of enthalpic differences was used to direct the synthesis of target compounds and, although all of the compounds calculated to afford S 2 that were prepared did yield diatomicsulfur, an isolable 1,2-dithietane other than dithiatopazine failed to materialize
对用于生成双原子硫 (S 2 ) 的稳定 1,2-二硫杂环丁烷衍生物的设计和合成进行了详细研究。焓差的计算机辅助评估用于指导目标化合物的合成,尽管计算出的所有化合物均能提供所制备的 S 2 确实产生了双原子硫,但除二硫托嗪之外的可分离 1,2-二硫杂环丁烷未能实现

point-to-axial chirality transfer reaction of optical dihydrophenanthrene-9,10-diols for the synthesis of axiallychiral diketones. Two sets of conditions, namely a basic tBuOK/air atmosphere and an acidic NaClO/n-Bu4NHSO4, were developed to oxidatively cleave the C-C bond, resulting in the formation of axiallychiralbiaryl diketones. Finally, brief synthetic applications of the obtained chiral aryl diketones
我们在此报道了光学二氢菲-9,10-二醇的点到轴手性转移反应,用于合成轴向手性二酮。开发了两组条件,即碱性 tBuOK/空气气氛和酸性 NaClO/n-Bu4NHSO4,以氧化裂解 CC 键,从而形成轴向手性联芳基二酮。最后,展示了所得手性芳基二酮的简要合成应用。
