Takasago Ligands and Complexes for Asymmetric Reactions

Catalyst for:

• Asymmetric hydrogenation of benzophenone
• Regio- and stereoselective preparation of axially chiral arylnaphthalene derivatives via rhodium-catalyzed [2+2+2] cycloaddition of diynes with naphthalenepropynoic acid derivatives in the presence of chiral biaryl bisphosphine ligands
• Regiodivergent rhodium-catalyzed [(2+2)+2] carbocyclization of 1,6-enynes with Me propiolates
• Ligand controlled regioselective and stereoselective desymmetrizing rhodium-catalyzed allylic arylation of meso cyclopentene dicarbonates with arylboronic acids to form regioisomeric arylcyclopentenols
• Platinum(II) complex-catalyzed enantioselective aldol reaction with ketene silyl acetals in DMF at room temperature
• Stereoselective preparation of chiral N,O-biaryls via Rh-catalyzed [2+2+2] cycloaddition of conjugate ynamides with diynes
