the β-position of aliphatic carboxylic acid derivatives with high enantioselectivities by the use of a commercially available chiral ligand is reported. N-Acylpyrrolidinones, as simple derivatives of an α,β-unsaturated carboxylic acid, were found to be the substrates of choice featuring good reactivity and high enantioselectivities (up to >99% ee).
报道了通过使用可商购的手性配体以高对映选择性将烷基片段引入脂族羧酸衍生物的β-位的新的实用方法。已发现作为α,β-不饱和羧酸的简单衍生物的N-酰基吡咯烷酮是具有良好反应性和高对映选择性(高达> 99%ee)的选择底物。
