In theory,instead, implementing chirality directly at the reactive metal center−exploiting the metal as a source of centrochirality− would be highly attractive since the close proximity of the metal to the coordinating substrate promises a highly effective transfer of chirality during the asymmetric induction.However, a considerable obstacle for the realization of such reactive chiral-at-metal asymmetric catalysts constitutes the retention of the relative and absolute metal-centered configuration during the reaction, since the coordination number at the metal varies during each catalytic cycle and thereby provides ample opportunities for the stereochemistry of the metal to scramble. |
