Efficient methods for the synthesis of chiral n,n+1-diamino acids starting from l-glutamic acid were developed. A second generation prototype amino acid based dendrimer, containing 1,3-propanediamine as the core and 4,5-diaminopentanoic acid as the branching unit, was synthesised following the divergent approach. Diaminobutane poly(propyleneimine) dendrimers modified at the periphery with n,n+1-diamino
开发了从 l-谷氨酸开始合成手性 n,n+1-二氨基酸的有效方法。采用发散方法合成了以 1,3-丙二胺为核心,以 4,5-二氨基戊酸为支链单元的第二代原型氨基酸树枝状大分子。合成并表征了在外围用 n,n+1-二氨基酸修饰的二氨基丁烷聚 (丙烯亚胺) 树枝状大分子。
