The investigation of the catalytic activity and stereoselectivity of ligand 10 was also carried out under another standard set of K〓Fe 〓 conditions (〓/ligand/substrate=0.002: 0.01: 1). The AD reaction of seven olefins gave corresponding diols in 72～99% yield (except for ethyl cinnamate, 48%) and 91～99% ees, which was comparable to those obtained from the reactions using the commercial ligand 〓PHAL.
