从“放大手性环境”的角度出发,宾夕法尼亚大学的化学家们已设计出增强对映选择性的催化剂。研究人员Walsh和Balsells打算通过手性环境的放大,使用一个单异构体催化剂配体的非对称中心来迫使又一个非手性配体采用非对称构象。催化反应的过渡金属离子的非对 From the perspective of “enlarging the chiral environment,” chemists at the University of Pennsylvania have devised catalysts that enhance enantioselectivity. Researchers Walsh and Balsells intend to use asymmetric centers of a single isomer ligand to force another achiral ligand to adopt an asymmetric conformation by enlarging the chiral environment. Catalytic reaction of transition metal ions not right
