A new copper(II) 2-ethylhexanoate-promoted addition of an alcohol and an amine across an alkene (oxyamination) is reported. The alcohol addition is intramolecular, while coupling with the amine occurs intermolecularly. Several 2-aminomethyl morpholines were synthesized in good to excellent yields and diastereoselectivities.
报道了一种新的 2-乙基己酸铜 (II) 促进的醇和胺在烯烃上的加成(氧胺化)。醇加成是分子内的,而与胺的偶联发生在分子间。合成了几种 2-氨基甲基吗啉,收率和非对映选择性都非常好。
