摘要:已经深入研究了在水性介质中蓝色 Led 光照射下芳香重氮盐和乙酸异丙烯酯之间的光催化 Meerwein 芳基化.在底物浓度,酯当量,共溶剂类型和用量,反应时间和光催化剂来源方面优化反应条件,允许使用 9-Mesityl 获得各种 1-Arylpropan-2-Ones,产率高达 95%-10-甲基吖啶高氯酸盐 ([acr-Mes]Clo 4). 接下来,通过将 Meerwein 芳基化与相应酮中间体的生物还原相结合,完成了单锅顺序光生物催化线性方法的设计.因此,根据醇脱氢酶的立体偏好,总共获得了 19 对 1-Arylpropan-2-Ol 对映异构体.全球收率高达 76%,立体选择性高至极佳(90 至 >99% Ee).此外,通过一锅三步顺序光生物催化方案,可以从苯胺开始获得两种 1-苯基丙-2-醇对映体(51-53% 产率).

标题 :Colormetric sensor compositions and methods
发明人：SESSLER JONATHAN; ANDRIOLETTI BRUNO; TRY ANDREW CARL; BLACK CHRISTOPHER
摘要:The present invention provides novel compounds exemplified by pyrrolic nitrogens used as anion and neutral species recognition elements with an aromatic core as a signal group. Described are methods for the synthesis of various pyrrole aryl compounds as well as various applications for these compounds. Methods of use include the binding and detection of specific analytes in a mixture and, in some examples, the separation of the analyte from the mixture. Additional methods of use include the transport of therapeutic agents and the sensing of components, degradants, and impurities in foodstuffs.
