Hong Li et al.
The Journal of organic chemistry, 73(18), 7398-7401 (2008-08-15)
Direct asymmetric aldol reaction of aryl ketones with aryl aldehydes catalyzed by chiral metal complex is reported for the first time herein. Two novel semicrown chiral ligands 1a and 1b were synthesized from (S)- and (R)-BINOL, respectively, and then employed

Chirality, 17(8), 476-480 (2005-08-17)
Optically active aminonaphthols derivatives are obtained by condensation of 2-naphthol, substituted benzaldehyde, and (S)-methylbenzylamine under mild conditions, without side products. Their absolute configurations are determined by X-ray crystallographic analysis. The addition of diethylzinc to aromatic aldehydes is considerably accelerated by

A strong asymmetric amplification is observed in the addition of diethylzinc on aromatic aldehydes in the presence of the bistriflamide of trans-1,2-diaminocyclohexane 3a. The asymmetric amplification originates from the insolubility of the catalyst precursor 3a of low enantiomeric excess (ee)
