Late-stage diversification of structurally complex peptides has enormous potential for drug discovery and molecular imaging. We report a simple, metal-free, late-stage reductive C2 alkylation of tryptophan and tryptophan-containing peptides using readily available 1,3-dithianes. This alkylation protocol has a wide substrate scope and an excellent tolerance for reactive functional groups.
结构复杂的肽的后期多样化在药物发现和分子成像方面具有巨大的潜力。我们报告了一种使用现成的 1,3-二噻烷对色氨酸和含色氨酸肽进行简单、无金属、后期还原 C2 烷基化的方法。该烷基化方案具有广泛的底物范围和对反应性官能团的优异耐受性。
