Rhodium-Catalyzed Asymmetric Synthesis of Indanones: Development of a New “Axially Chiral” Bisphosphine Ligand
摘要:
A rhodium-catalyzed asymmetric isomerization of racemic alpha-arylpropargyl alcohols to beta-chiral indanones has been developed. High enantioselectivity has been realized by the use of a newly developed axially chiral bisphosphine ligand. This ligand is unique in the sense that its axial chirality is fixed to a single configuration upon complexation to a transition metal due to other chiral axes existing within the same molecule.
