Photoaffinity tags can be incorporated easily into peptoids and congeners by the Ugi and Passerini multicomponent reactions. Products related to photo-methionine and photo-leucine can be accomplished by diazirine-containing building blocks. The same protocols can be used to synthesize derivatives with benzophenone photo cross-linkers.
通过 Ugi 和 Passerini 多组分反应,光亲和标签可以很容易地加入到类肽和同系物中。与光蛋氨酸和光亮亮氨酸有关的产品可以通过含重氮氨酸的构建模块来完成。同样的方法也可用于合成含有二苯甲酮光交联剂的衍生物。
