本报告有助于理解携带 N-保护的叔亮氨酸配体的手性二铑 (II) 羧酸盐催化剂的立体选择性。研究了配体立体纯度对催化剂结构和对映选择性的可能影响。 Rh-2(S,S,S,R-PTTL)(4) 非对映异构体的新 X 射线晶体结构证明了这一点。
The current report contributes to the understanding of the stereoselectivity of chiral dirhodium(II) carboxylate catalysts carrying N-protected tert-leucine ligands. Investigating the possible effect of ligand stereo-purity on catalyst structure and enantioselectivity was carried out. This was justified through a new X-ray crystal structure for Rh-2(S,S,S,R-PTTL)(4) diastereomer.
