peptides remains in demand as it represents a promising approach for further structural diversification of peptides. Herein, we describe the Pd(II)-catalyzed C(sp3)-H alkynylation of Ala-Asn-embedded di- and tripeptides using Asn as the endogenous lead group. In addition, a key building block for the glycopeptide Tyc4PG-14 and Tyc4PG-15 was produced by our methodology.
将炔部分引入肽中仍然存在需求,因为它代表了肽进一步结构多样化的有前途的方法。在此,我们描述了使用 Asn 作为内源先导基团的 Pd(II) 催化的 Ala-Asn 嵌入的二肽和三肽的 C(sp 3 )-H 炔基化。此外,我们的方法还生产了糖肽 Tyc4
PG-14 和 Tyc4
PG-15 的关键构建模块。
