array of 30 β-amino acids of high enantiomeric purity using the conjugate addition of homochiral lithium N-benzyl-N-(α-methylbenzyl)amide as the key step is accomplished. The experimental simplicity and highly practical nature of the protocol is demonstrated by the efficient parallel conversion of 15 α,β-unsaturated esters to both enantiomeric series of the corresponding β-amino acids in high overall
使用高手性锂N-苄基-N-(α-甲基苄基)酰胺的共轭加成,完成了对映体纯度高的30个β-氨基酸阵列的平行不对称合成。该协议的实验简单性和高度实用性通过高15种α,β-不饱和酯的高效平行转化为相应β-氨基酸的对映体系列以高总收率和选择性进行了证明,且每个步骤的纯化步骤最少反应方案。
