  iron(III) triflimide allowed the efficient thiolation of a range of arenes, including anisoles, phenols, acetanilides, and N-heterocycles. The method was applicable for the late-stage thiolation of tyrosine and tryptophan derivatives and was used as the key step for the synthesis of pharmaceutically relevant biaryl sulfur-containing compounds such as the antibiotic dapsone and the antidepressant vortioxetine

  carboxamides are valuable in pharmaceutical applications, the preparation N-(indol-2-yl)amides with similar structures continues to be challenging. Herein we report on visible-light-induced late-stage photoredox C–H amidation with N-unprotected indoles and tryptophan-containing peptides, leading to the formation of N-(indol-2-yl)amide derivatives.

  N-未保护的吲哚的后期功能化可用于修饰低分子量药物和生物活性肽。吲哚羧酰胺在医药应用中很有价值，而具有相似结构的N-（吲哚-2-基）酰胺的制备仍然具有挑战性。本文中我们报道了可见光诱导的后期光氧化还原C–H酰胺化与N-未保护的吲哚和含色氨酸的肽，导致N的形成-（吲哚-2-基）酰胺衍生物。通过在室温下用绿色发光二极管照射，可以将含有吸电子基团的N-未保护的吲哚和芳氧基酰胺直接偶联至曙红Y作为光催化剂。机理研究和密度泛函理论计算表明，这种转变可能通过吲哚从PS *到PS •–循环的C–H氧化功能化而进行。该协议为N-未保护的吲哚衍生物的后期修饰标记和肽-药物结合提供了一个新的工具包。

  Born to be mild: The general, direct and selective C2 arylation of native Trp‐containing peptides can be achieved by palladium‐catalyzed CH activation with aryl iodides in water, under microwave irradiation for a short time (see scheme). Under these mild conditions, the structural and stereochemical integrity of peptides is preserved.

  reaction of C‐terminal thioacids derived from protected amino acids and peptides with the Sanger reagent and other electron‐deficient aryl halides in the presence of a free amine immediately form a peptide bond with the amine. This essentially epimerization‐free method was used for the 4+4 block synthesis of a hindered octapeptide (see scheme; Boc, Pbf, and Trt are protecting groups).

  Hydrogen‐bond mediated coupling of 1,2,3‐triazoles to indoles and pyrroles results in N2 selective functionalization of the triazole moiety in moderate to excellent yields. The reaction was tolerant of un‐, mono‐ and disubstituted triazoles and was applied to synthesize tryptophan derived fluorescent amino acids.
