The asymmetric synthesis of 2-amino-5-hydroxycaprolactam derivatives is essential for exploring the antitumor properties of ester-bearing bengamides. In this study, chiral caprolactam isomers were achieved on the basis of highly E-selective Wittig olefination, asymmetric oxidations of the E-enol ethers, reductive amination of the aldehyde derivatives, cyclization of the 5-hydroxylysine analogues or/and
2-氨基-5-羟基己内酰胺衍生物的不对称合成对于探索含酯的苯甲酰胺的抗肿瘤特性至关重要。在这项研究中,手性己内酰胺异构体是在高度E-选择性Wittig烯化,E-烯醇醚的不对称氧化,醛衍生物的还原胺化,5-羟基赖氨酸类似物的环化或/和脱保护的基础上获得的。 己内酰胺- ë -选择性烯-不对称氧化-烯醇醚-还原性胺化
