paper describes a multicomponent approach to novel totally protected precursors of PNA-monomers via Ugi 4CC. The obtained bisamides are converted into several partially protected PNA-monomers or derivatives thereof using three different procedures. Methods for hydrolysis are shown to be dependent on the nature of the isocyano component required for Ugi 4CC. Several novel monomers suitable for oligomer
本文介绍了一种多组分方法,可通过Ugi 4CC对新型完全保护的PNA单体前体进行处理。使用三种不同的方法将获得的双酰胺转化为几种部分保护的PNA单体或其衍生物。已显示水解方法取决于Ugi 4CC所需的异氰基组分的性质。制备了几种适用于低聚物合成的新型单体,证明了该反应序列的高通用性。
