selective aromatic deuteriation of various sulfonylureas and tertiary sulfonamides, as well as for a broad range of secondary sulfonamides. Based on a comprehensive screening of readily available Ir catalysts, the Kerr-type NHC catalyst 5 proved to be most efficient in the HIE reaction of secondary sulfonamides and sulfonylureas. However, for tertiary sulfonamides, the commercially available Burgess catalyst
我们首次报告了各种磺酰脲类和叔磺酰胺以及各种仲磺酰胺的选择性芳烃氘化的优化氢同位素交换 (HIE) 条件。基于对容易获得的 Ir 催化剂的全面筛选,证明 Kerr 型 NHC 催化剂 5 在仲磺酰胺和磺脲类的 HIE 反应中最有效。然而,对于叔磺酰胺,尚未用于 HIE 反应的市售 Burgess 催化剂 6 导致氘的掺入量高得多。最后,我们测试了用于标记一系列磺胺药物的新 HIE 协议,并调整了条件以允许选择性氚标记。
Novel ramoplanin derivatives are disclosed. These ramoplanin derivatives exhibit antibacterial activity. As the compounds of the subject invention exhibit potent activities against gram positive bacteria, they are useful antimicrobial agents. Methods of synthesis and of use of the compounds are also disclosed.
