As a new strategy for the optimization of a chiral catalyst, the catalytic activity of the host-guest complexes of chiral bisphosphine bearing imidazolidinone was investigated in Rh-catalyzed asymmetric hydrogenation of enamide. Marginal enhancement in enantioselectivity was observed and the nature of interaction between host-guest was experimentally elucidated.
作为优化手性催化剂的一种新策略,研究人员在 Rh 催化的烯酰胺不对称氢化反应中研究了手性
双膦咪唑烷酮的主-客配合物的催化活性。观察到对映体选择性略有提高,并通过实验阐明了主-客体之间相互作用的性质。
