for the generation of libraries of structurally diverse compounds. Hyp can be cleaved at two points, followed by the introduction of new functionalities. In the first cycle, the removal and replacement of the carboxylic group are carried out, followed (second cycle) by the scission of the 4,5-position and manipulation of the resulting chains. In this way, three new chains are generated and can be transformed
容易获得,低成本的4 - [R羟基升-脯氨酸(Hyp)作为“双重可定制”单元引入,用于生成结构多样的化合物的库。Hyp可以分为两点,然后引入新功能。在第一个循环中,进行羧基的去除和置换,然后(第二个循环)进行4,5-位的断裂和所得链的操作。以这种方式,产生了三个新链并且可以独立地转化以提供具有定制取代基的多种产物,例如β-氨基醛,二胺,β-氨基酸衍生物,包括N-烷基化的或修饰的肽。这些产品中许多都是高利润的化合物,尽管具有商业价值,但仍很稀缺。此外,该过程在立体化学控制下进行R或S异构体的合成路线变化很小。
