Three achiral branching units 1−3 derived from α,α-bis(aminomethyl)-β-alanine were synthesized and evaluated in the construction of branched and sterically compact β-peptide conjugates on a solid support. Several peptide conjugates bearing an N-alkylated 1,2,3,4-tetrahydroisoquinoline moiety were prepared to demonstrate the applicability of the branching units in a solid phase peptide synthesis. The
合成了三个衍生自α,α-双(氨基甲基)-β-丙氨酸的非手性分支单元1-3,并在固体支持物上构建了支链且空间紧凑的β-肽共轭物。制备了带有N-烷基化的1,2,3,4-四氢异喹啉部分的几种肽缀合物,以证明支化单元在固相肽合成中的适用性。最有用的结构单元3在N-邻苯二甲酰-β-丙氨酸的α-碳上结合了Boc保护的氨基甲基侧链。
