The diastereoselective nucleophilic addition of alkyllithium to N-alkylidene-alpha-naphthylethylamine was carried out. In the presence of Lewis acids or Lewis bases, organolithiums reacted smoothly with imines to give the corresponding amines in high stereoselectivity (up to 100% de). Furthermore, the resulting optically active amines were found to be useful for asymmetric reactions as chiral ligands
进行烷基锂到N-亚烷基-α-萘乙胺的非对映选择性亲核加成。在路易斯酸或路易斯碱的存在下,有机锂与亚胺平稳反应,以高立体选择性(最高100%de)生成相应的胺。此外,发现所得的光学活性胺作为手性配体可用于不对称反应。
