  Although defluorinative functionalization of trifluoromethylarenes has been studied by several research groups, different kinds of catalysts are required accordingly based on specific substrate families to obtain the corresponding RCF2Ar compounds. Herein, we report a general photocatalytic approach for the selective hydrodefluorination (HDF) and defluoroalkylation (DFA) of ArCF3. Using electronically-different

  尽管多个研究小组对三氟甲基芳烃的脱氟官能化进行了研究，但根据特定的底物族，需要相应不同种类的催化剂才能获得相应的RCF 2 Ar化合物。在此，我们报告了一种用于ArCF 3选择性加氢脱氟（HDF）和脱氟烷基化（DFA）的通用光催化方法。使用电子不同的芳烃硫醇盐作为光敏剂，从多种电子可变的三氟甲基芳烃（包括天然产物和生物活性分子）合成了 88 种 α,α-二氟甲基化合物。我们的机理研究揭示了光诱导的电子供体-受体 (EDA) 络合，然后是硅烷辅助的 C-F 键激活。

  This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt and/or hydrate and/or prodrug of the compound) that modulate (e.g., agonize) the apelin receptor (also referred to herein as the APJ receptor; gene symbol APLNR). This disclosure also features compositions containing the same as well as other methods of using and making the same. The chemical entities are useful, e.g., for treating a subject (e.g., a human) having a disease, disorder, or condition in which a decrease in APJ receptor activity (e.g., repressed or impaired APJ receptor signaling; e.g., repressed or impaired apelin-APJ receptor signaling) or downregulation of endogenous apelin contributes to the pathology and/or symptoms and/or progression of the disease, disorder, or condition. Non-limiting examples of such diseases, disorders, or conditions include: (i) cardiovascular disease; (ii) metabolic disorders; (iii) diseases, disorders, and conditions associated with vascular pathology; and (iv) organ failure; (v) diseases, disorders, and conditions associated with infections (e.g., microbial infections); and (vi) diseases, disorders, or conditions that are sequela or comorbid with any of the foregoing or any disclosed herein. More particular non-limiting examples of such diseases, disorders, or conditions include pulmonary hypertension (e.g., PAH); heart failure; type II diabetes; renal failure; sepsis; and systemic hypertension.
