There is high demand for new methods to modify peptides, for application in drug discovery and biomedicine. A C–H functionalization protocol for the olefination of tryptophan residues in peptides is described. The modification is successful for Trp residues at any position in the peptide, has broad scope in the styrene coupling partner, and offers opportunities for conjugating peptides with other biomolecules
对于用于药物发现和生物医学的修饰肽的新方法有很高的要求。描述了用于肽中色氨酸残基的烯化的AC–H功能化方案。修饰对于肽中任何位置的Trp残基都是成功的,在苯乙烯偶联伴侣中具有广泛的适用范围,并提供了将肽与其他生物分子缀合的机会。对于同时含有Trp和Phe的肽,指导基团操纵可完全控制残基的选择性。
