Chen, Hui,Wang, Qiao Feng,Sun, Xiao Li,Luo, Jing,Jiang, Ru
experimental part, p. 104 - 105 (2010/06/21)
Cinchona alkaloid ester derivatives were adopted to asymmetric dihydroxylation and asymmetric aminohydroxylation reactions in excellent yields and enantiomeric excesses.
Second-generation DBFOX ligands for the synthesis of β-substituted α-amino acids via enantioselective radical conjugate additions
Banerjee, Biplab,Capps, Steven G.,Kang, Junghoon,Robinson, Joshua W.,Castle, Steven L.
experimental part, p. 8973 - 8978 (2009/04/11)
(Chemical Equation Presented) A set of second-generation DBFOX ligands possessing extended aryl or benzyl-type groups was synthesized. The requisite amino alcohols were either commercially available (DBFOX/Bn) or constructed via Sharpless asymmetric amino

Optically pure new Evans auxiliary analogs, (4R)- and (4S)-4-(2-naphthyl)oxazolidin-2-one, have been synthesized by using the Sharpless catalytic asymmetric aminohydroxylation reaction (Sharpless AA). The concise two-step synthesis involves a unique solution-to-solid Sharpless AA process and new neat cyclization conditions.
