The first palladium-catalyzed diastereoselective conjugate addition of arylboronic acids to chiral imides is reported. The catalytic system employing 4-tert-butyloxazolidin-2-one as the chiral auxiliary in a mixed solvent system of MeOH/H2O (1:3) under an air atmosphere provides the optically active 3-arylbutanoic acid derivatives in excellent yields with high diastereoselectivity.
Diastereoselection in the conjugate additions of organocopper reagents to N-enoyloxazolidinones
Williams, David R.,Kissel, William S.,Li, Jie Jack

A survey of conjugate additions of Yamamoto organocopper reagents to N- enoyl-4-substituted oxazolidinones is reported. Diastereofacial selectivity is reversed for 4-phenyl and 4-benzyloxazolidinones of the same relative configuration. Alkenylcopper reage
Diastereospecific tandem Michael-like addition/electrophilic bromination: A one-pot tandem asymmetric synthesis of precursors of unusual amino acids
Li,Jarosinski,Hruby
, p. 2561 - 2564 (2007/10/02)
A systematic series of key intermediates of unusual β-methyl-amino acids have been synthesized by using a modified Evans auxiliary in an asymmetric Michael-like reaction followed by direct bromination in a one-pot reaction.
