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, asymmetricoxidations of the E-enol ethers, reductive amination of the aldehyde derivatives, cyclization of the 5-hydroxylysine analogues or/and
