Rh(I)-catalyzed asymmetric hydrosilylation and hydroboration/oxidation reactions using berens ligand
Marques, Carolina S.,Burke, Anthony J.
experimental part, p. 4207 - 4214 (2009/04/06)
The Berens ligand 2 was used in a number of Rh(I)-catalyzed asymmetric hydrosilylations of acetophenones under standard conditions, affording the corresponding 1-arylalcohols in ees up to 65%. Some novel Rh catalysts were generated in situ from the neutral precatalyst [Rh(μ-Cl)(COD)]2 and screened in the catalytic asymmetric hydroboration/oxidation of styrenes, gave enantioselectivities of up to 62%.

Acyclic stereoselective boron alkylation reactions for the asymmetric synthesis of β-substituted α-amino acid derivatives
O'Donnell, Martin J.,Cooper, Jeremy T.,Mader, Mary M.
, p. 2370 - 2371 (2007/10/03)
Optically active syn- or anti-β-substituted-α-amino acid derivatives are prepared in 94 to ≥99% ee and 66-98% ds by reaction of the Schiff base acetate of glycine tert-butyl ester with chiral, nonracemic B-alkyl-9-BBN derivatives in the presence of the Cinchona alkaloid, cinchonidine (CdOH) or cinchonine (CnOH), base, and lithium chloride.
