Benzylamines belong to an important class of building blocks in the synthesis of biologically active natural products and drugs. Encumbered by amide-directed -C-H activation, remote -selective C-H functionalization of benzylamines has hitherto not been realized to date. Here, we report a palladium-catalyzed -selective C-H olefination and acetoxylation of benzylamines using a functionalized benzoyl template. Enhancing the coordination strength of the directing group in the template significantly improved the site selectivity of C-H functionalization.

Synergistic effect of scattered rare metals on Pt/CeO for propane oxidative dehydrogenation with CO.

The oxidative dehydrogenation of propane with CO (CO-ODP) is a green industrial process for producing propene. Cerium oxide-supported platinum-based (Pt/CeO) catalysts exhibit remarkable reactivity toward propane and CO due to the unique delicate balance of C-H and C[double bond, length as m-dash]O bond activation. However, the simultaneous activation and cleavage of C-H, C-C, and C-O bonds on Pt/CeO-based catalysts may substantially impede the selective activation of C-H bonds during the CO-ODP process.

Benzo-fused γ-lactams are fundamental in medicinal chemistry, acting as essential elements for various therapeutic agents due to their structural adaptability and capability to enhance biological activity. In their synthesis, transition metals play a pivotal role as catalysts, offering more efficient alternatives to traditional methods by facilitating C-N bond formation through mechanisms like intramolecular coupling. Recent advances have especially spotlighted transition-metal-catalyzed C-H amination reactions for directly converting C(sp)-H to C(sp)-N bonds, streamlining the creation of these compounds.

The selective amination of aromatic C-H bonds is a powerful strategy to access aryl amines, functionalities found in many pharmaceuticals and agrochemicals. Despite advances in the field, a platform for the direct, selective C-H amination of electronically diverse (hetero)arenes, particularly electron-deficient (hetero)arenes, remains an unaddressed fundamental challenge. In addition, many (hetero)arenes present difficulty in common selective pre-functionalization reactions, such as halogenation , or metal-catalyzed borylation and silylation .

Radiotherapeutics, clonal hematopoiesis, and risk of hematologic malignancies: The good, the bad, the ugly.

While radiotherapeutics have demonstrated significant clinical benefit across multiple cancer types including thyroid cancer, neuroendocrine tumors, and prostate cancer, hematological toxicities can be frequent and challenging. It remains unknown to what extent the hematologic toxicity is driven by clonal processes that preexist and are selected for by treatment induced selection pressures. In this review, we discuss the background leading to the adoption of radiotherapeutics in the treatment of solid tumor malignancies, the risk of hematologic toxicities and myeloid neoplasms and the evidence pointing to potential precursor lesions that may predispose patients to hematologic toxicities.
