showed good performance in enantioselective intramolecular Rauhut–Currier reaction of bis(enones), giving the corresponding products in good yield with up to 98% ee. Moreover, with amino acid derived amide-phosphine B3, optically active α-methylene-δ-valerolactone was obtained in 88% yield and > 99.9% ee utilizing the enantioselective intramolecular Rauhut-Currier reaction of chalcone derivative.
已经设计和合成了三系列新颖的基于二茂铁的双官能手性膦。硫脲磷化氢A7在双(烯酮)对映选择性分子内的Rauhut-Currier反应中显示出良好的性能,以高达98%ee的产率提供了相应的产物。此外,利用氨基酸衍生的酰胺-膦B3,利用查尔酮衍生物的对映选择性分子内Rauhut-Currier反应,以88%的收率和> 99.9%ee的ee获得了光学活性的α-亚甲基-δ-戊内酯。
