摘要:在此,我们报告了镍催化的 3-丁烯基氨基甲酰氯与伯烷基碘的还原交叉偶联反应,以获得具有广泛底物范围和高 Ee 的手性 α-烷基化吡咯烷酮.目前的合成技术对吡咯烷酮的对映选择性 α-单烷基化仍然具有挑战性.新设计的手性 8-喹啉咪唑啉配体(quinim)对于保持反应性和对映选择性至关重要,以确保单取代烯烃的还原环化,从而前所未有地合成手性非芳香杂环.

标题:Process for the preparation of 1,1,2,2-tetrahydroperfluoroalkanols and their esters
发明人：LANTZ ANDRE; MICHAUD PASCAL
权利人:ATOCHEM
摘要:The invention relates to the synthesis of 1,1,2,2-tetrahydroperfluoroalkanols and their esters by oxidizing a 2-(perfluoroalkyl)ethyl iodide using hydrogen peroxide in a carboxylic acid or carboxylic acid ester in the presence of sulphuric acid. n In the process according to the invention, from 1 to 30 moles of sulphuric acid, from 1 to 50 moles of carboxylic acid or of an ester of such an acid, and from 3 to 20 moles of hydrogen peroxide per mole of 2-perfluoralkyl)ethyl iodide are used.
