摘要:长期以来,外消旋体的自发拆分,从天然化合物到人造结构,一直被人们所追求,以揭示生命中同手性的起源.尽管已经精心设计了多种合成系统来阐述自发对称性破缺的基本原理,但它们的复杂性仍然无法与包括 Dna 螺旋和蛋白质在内的自然杰作相比,它们在分子和超分子水平上都表现出显着的聚结作用.在这里,我们报告了从包含 720 种可能的立体异构体的三重联锁笼状链烷的外消旋混合物中自发拆分出一对纯手性实体.该笼状链烷包含六个含甲基二噻烷环的连接基(表示为rac-2 ).由于每个甲基二噻烷环都有两个手性中心,因此它表现出四种可能的非对映体.这些等摩尔的非对映异构体优先与它们的轴向类似物相比赤道构象异构体进行区分,导致( S,R )-2和( R,S )-2的主要形成,即分子水平上的非对映异构体富集.这种非对映体富集无偏从前体rac-2转移到笼状链烷rac-4,其中一对同手性化合物 ( S
