Pd-catalyzed site-selective C(sp)-H olefination and alkynylation of phenylalanine residues in peptides are described. The amino acids within the peptides are used as native bidentate directing groups to facilitate C-H functionalization. This protocol would provide appealing strategies for the postsynthetic modification of peptides.
Pd 催化的肽中苯丙氨酸残基的位点选择性 C(sp)-H 烯基化和炔基化反应被描述。肽中的氨基酸被用作原生双齿导向基团,以促进 C-H 官能化。该方案将为肽的后期合成修饰提供有吸引力的策略。
