T. Benincori et al., (DIPHENYLPHOSPHINO)-BIHETEROARYLS - THE FIRST EXAMPLE OF A NEW CLASS OF CHIRAL ATROPISOMERIC CHELATING DIPHOSPHINE LIGANDS FOR TRANSITION-METAL-CATALYZED STEREOSELECTIVE REACTIONS, Journal of the Chemical Society, Chemical Communications, (6), 1995, pp. 685-686
Ruthenium(ii) dichloride complexes with (+)- and s(diphenylphosphino)-
4,4',6,6'-bibenzo[b]thiophene (1a), new chiral atropisomeric heterocyc
lic ligands, reduce alpha- and (beta-oxoesters to alpha- and beta-hydr
oxyesters with an enantiomeric purity comparable, if not higher, to th
at reported for binap under the same experimental conditions.
