strategy for constructing maleimide-containing peptides and cyclic peptides using Rh(III)-catalyzed tryptophan (Trp) (C7) alkenylation, which is challenging due to the inherent reactivity of the indole benzenoid ring. This method is scalable and exhibits broad substrate scope. The utility of this protocol could further be demonstrated by the synthesis of peptide conjugates with natural products and amino
在这里,我们报告了一种使用 Rh(III) 催化的色氨酸 (Trp) (C7) 烯基化构建含马来酰亚胺肽和环肽的新策略,由于吲哚苯环的固有反应性,该策略具有挑战性。该方法具有可扩展性,并具有广泛的底物适用范围。该协议的实用性可以通过天然产物和氨基酸的肽结合物的合成以及马来酰亚胺支撑环肽的构建得到进一步证明。
