  • Synthesis of aryl serines
    Patent number: 6057473
    Abstract: Anthraquinone chiral ligands (AQN) are used in asymmetric aminohydroxylation addition reactions of cinnamate based olefins for synthesizing aryl serines. The anthraquinones impart a reverse regioselectivity as compared to the commonly employed phalazine chiral ligands (PHAL). Carbamates are employed as the oxidant nitrogen source. The yields and enantiomeric efficiencies are Excellent. .beta.-Hydroxyamines are obtained by deprotecting the corresponding .beta.-hydroxycarbamate.
