A versatile solid-phase approach to sequence-defined polyamidoamines was developed. Four different Fmoc-polyamino acid building blocks were synthesized by selective protection of symmetrical oligoethylenimine precursors followed by introduction of a carboxylic acid handle using cyclic anhydrides and subsequent Fmoc-protection. The novel Fmoc-polyamino acids were used to construct polyamidoamines demonstrating
开发了一种通用的固相方法,用于确定序列的聚酰胺胺。四种不同的Fmoc-聚氨基酸结构单元是通过对对称的低聚乙炔亚胺前体进行选择性保护,然后使用环酐引入羧酸的处理方法以及随后的Fmoc保护来合成的。新型Fmoc-聚氨基酸用于构建聚酰胺酰胺,证明与标准Fmoc反应条件完全相容。结构单元的直接合成和固相偶联反应的高效率使所定义的聚阳离子的多功能合成成为可能。
