Description

Application

Takasago Ligands and Complexes for Asymmetric Reactions

(S)-T-BINAP reacts with silver nitrate to form (S)-Tol-BINAP·AgNO₃, which can catalyze the enantioselective allylation reaction of aldehydes to form enantiopure secondary alcohols. It may be used as a chiral ligand in the palladium catalyzed asymmetric double carbohydroamination of iodoarenes to form α-aminoamides. It can also catalyze the asymmetric N-allylation reaction of ortho-tert-butylanilide derivatives with diallyl carbonate to form chiral N-allyl ortho-tert-butylanilides.
