We describe the synthesis of new hydrazinoPNA (hydPNA) monomers and new hydPNA-containing dimers. For the hydPNA monomers, the primary terminal amino group of the aminoethylglycine unit of classical aegPNA is replaced by a hydrazine moiety. An appropriate choice of two orthogonal protecting groups on the two hydrazine nitrogen atoms makes it possible to drive their coupling with other monomers selectively
我们描述了新的hydrazinoPNA(hyd PNA)单体和新的hyd PNA含二聚体的合成。对于hyd PNA单体,经典aeg PNA的氨基乙基甘氨酸单元的伯末端氨基被肼部分代替。在两个肼氮原子上的两个正交的保护基团的适当选择,能够以驱动它们的耦合与选择性地在一个其它单体或其他的氮原子,从而获得两种不同类型的PNA二聚体。这些二聚体代表了新的构建基块,可用于生成新型PNA低聚物。
