传统上,用于不对称催化的配体含有立体原子或受阻单键(阻转异构),或两者。在这里,我们证明了联烯,手性1,2-二烯,附加基本功能可以作为过渡金属的配体。我们描述了一种含联烯的双膦,当与Rh(I)配位时,它促进芳基硼酸对α-酮酯的不对称加成,具有高的对映选择性。溶液和固态结构分析表明,联烯中的一个烯烃可以与过渡金属配位,生成二齿和三齿配体。
Traditionally, ligands used in asymmetric catalysis have contained either stereogenic atoms or hindered single bonds (atropisomerism), or both. Here we demonstrate that allenes, chiral 1,2-dienes, appended with basic functionality can serve as ligands for transition metals. We describe an allene-containing bisphosphine that, when coordinated to Rh(I), promotes the asymmetric addition of aryl boronic acids to α-keto esters with high enantioselectivity. Solution and solid-state structural analysis reveals that one olefin of the allene can coordinate to transition metals generating bi- and tri-dentate ligands.
