An asymmetric synthesis of cyclic amino acids having piperidine and azepane core structures was realized starting from readily available glycine and alanine esters by combination of phase-transfer catalyzed asymmetric alkylation and subsequent reductive amination.
通过相转移催化不对称烷基化和随后的还原胺化反应,从易得的甘氨酸和丙氨酸酯出发,实现了具有哌啶和氮杂环庚烷核心结构的环状氨基酸的不对称合成。
