A series of highly efficient and inexpensive bioxazoline ligands were easily synthesized from tartaric acid and further explored for enantioselective addition of terminal alkynes to imines in combination with copper(II) salts. This is the first ever report showing application of bidentate bioxazoline ligands in the synthesis of propargylamines with good enantioselectivity.
易于从酒石酸合成一系列高效且廉价的生物恶唑啉配体,并进一步探索了将末端炔烃与铜(II)盐组合对映选择性加成至亚胺的方法。这是有史以来第一个报告,显示双齿生物x唑啉配体在具有良好对映选择性的炔丙基胺合成中的应用。
