A new chiral oxazaborolidine catalyst was prepared in situ from 3,5-bis(trifluoromethyl)phenylboron dichloride and N-(p-toluenesulfonyl)-(S)-tryptophan. This catalyst is much more active than Corey's original catalyst for the Mukaiyama aldol reaction of a

, p. 463 - 466 (2007/10/03)
The novel chiral diaqua palladium(II) complexes of (R)-BINAP 9a and (R)-Tol-BINAP 9b were prepared in good yield, and their structures were determined by X-ray crystallography. These air-and moisture-stable complexes were found to be excellent catalysts f
