A new tertiary pseudo C2-symmetric 1,2-diamine derived from (1S,2S)-(+)-pseudoephedrine was synthesized and tested in the enantioselective addition of MeLi to aromatic imines. A comparative study with the analogous C2-symmetric ligand successfully used previously in the same reaction showed comparable selectivity and better reactivity for this novel diamine.
合成了一种新的由(1 S,2 S)-(+)-伪麻黄碱衍生的三级伪C 2对称的1,2-二胺,并经MeLi对映选择性加成到芳族亚胺中进行了测试。先前在同一反应中成功使用的类似C 2对称配体的比较研究表明,该新型二胺具有相当的选择性和更好的反应性。
