The synthesis of branched peptides from cyanomethylenamino pseudopeptides, via catalytic hydrogenation in the presence of amino acid derivatives, is described. When the inserted amino acid was a glycine derivative, the resulting branched peptide lactamized in situ to 2-oxopiperazine derivatives. This new C-backbone peptide branching approach is compatible with the diversity of amino acid side chains
描述了由氰基亚甲基氨基伪肽通过在氨基酸衍生物存在下的催化氢化合成支链肽。当插入的氨基酸是甘氨酸衍生物时,所得的支链肽原位内酰胺化为2-氧代哌嗪衍生物。这种新的C骨干肽分支方法与氨基酸侧链的多样性兼容。
