The synthesis and application of a newly designed C2-symmetric chiral bifunctional triamine family (C2-CBT) is reported. These enantiopure chiral triamine scaffolds can be accessed in multigram amounts from simple amino acids while avoiding chromatographic purification. As a proof of principle, C2-CBT has been studied in the aldol reaction of cyclic ketones with isatins, with the target tertiary alcohols
报道了新设计的C 2对称手性双官能三胺三胺家族(C 2 -CBT)的合成和应用。这些对映体纯的手性三胺支架可以从简单氨基酸中以数克的量获得,同时避免色谱纯化。作为原理的证明,已经在环状酮与靛红的醛醇缩合反应中研究了C 2 -CBT,并以高效的方式形成了目标叔醇。已经通过简单的提取技术回收了催化剂,并随后进行了再利用。
