Orthogonally protected bis(aminomethyl)malonic acid (1) was synthesized and used as a key building block for the construction of cyclic peptide conjugates on a solid support. The applicability of the building block was demonstrated by preparation of 19 backbone cyclized/branched peptide conjugates of N-2-alkyl-5-(3-aminopropoxy)-1,2,3,4-tetrahydroisoquinoline as stereoisomeric pairs.
合成了正交保护的双(氨基甲基)丙二酸(1),并用作在固体支持物上构建环肽缀合物的关键组成部分。通过制备N -2-烷基-5-(3-氨基丙氧基)-1,2,3,4-四氢异喹啉作为立体异构体对的19个骨架环化/支化的肽缀合物,证明了该结构单元的适用性。
