Bicyclic lactams, suitable for incorporation into conformationally restricted peptide mimics, can be synthesized by using olefinic starting materials for the Ugi multicomponent reaction, setting up an olefin metathesis reaction, that is easily carried out with the Grubbs catalyst. The influence of the different starting materials is evaluated. In addition, the utilization of chiral, nonracemic amines
适用于构象受限的肽模拟物的双环内酰胺可以通过使用用于Ugi多组分反应的烯烃原料,建立烯烃复分解反应来合成,这很容易用Grubbs催化剂进行。评估了不同原料的影响。另外,描述了手性非外消旋胺的利用。
