bisoxazoline ligands with a bipyridinyl backbone were prepared with ease from 3,3′-dicarbomethoxy-2,2′-bipyridine and enantiomerically pure 2-amino alcohols via a corresponding amide as intermediate. Interestingly, when these ligands were coordinated with Pd(II) and Cu(I), different complexation behaviors were found.
通过3,3'-二甲氧基甲氧基-2,2'-联吡啶和对映体纯的2-氨基醇通过相应的酰胺作为中间体轻松制备了具有联吡啶骨架的新型C 2对称手性双恶唑啉配体。有趣的是,当这些配体与Pd(II)和Cu(I)配合时,发现了不同的络合行为。
