  摘要：

  我们采用了一系列设计良好吸收肾素抑制剂的经验准则，我们遵循了两种策略来提高药效并同时保持生物利用度。一种方法涉及掺入带有弱碱性取代基的延伸的N-末端残基，并以化合物25为例。另一种方法集中于包含N-末端磺酰胺并最终发现抑制剂32（A-72517）。25和32均在大鼠和雪貂中表现出极佳的生物利用度（> 25％），并且在猴子中受到肝脏清除后，在该物种中有效。

  The highly enantioselective sulfa-Michael addition of alkyl thiols to unactivated α-substituted acrylate esters catalyzed by a bifunctional iminophosphorane organocatalyst under mild conditions is described. The strong Brønsted basicity of the iminophosphorane moiety of the catalyst provides the necessary activation of the alkyl thiol pro-nucleophile, while the two tert-leucine residues flanking a

  A series of novel multi (bi-/tri-/tetra-)-dentate phosphines with good robustness against water and oxygen were synthesized and fully characterized. It was found that the developed ionic tri-dentate phosphine (L2′) enabled Pd-catalyzed alkoxycarbonylation of alkynes most efficiently while H2O was used as an additive instead of acid. As for L2′, its unique steric configuration with two types of potential

  Reported herein is a practical method for macrolactam synthesis via a Rh(III)-catalyzed ring closing alkene–alkene cross-coupling reaction. The reaction proceeded via a Rh-catalyzed alkenyl sp2 C–H activation process, which allows access to macrocyclic molecules of different ring sizes. Macrolactams containing a conjugated diene framework could be easily prepared in high chemoselectivities and Z,E

  functionality has been reliably transferred into nucleophilic radicals with the loss of one molecule of formaldehyde. Intriguingly, we found that the dehydroxymethylation process can be significantly promoted by the cerium catalyst, and the stabilization effect of the fragmented radicals also plays a significant role. This operationally simple protocol has enabled the direct utilization of primary alcohols as unconventional

  脱羟甲基化是将醇原料直接转化为少一个碳原子的烷基合成子，是一种利用醇材料的普遍性和稳健性的非常规且未充分探索的策略。在温和且氧化还原中性的反应条件下，利用廉价的铈催化剂，提供了光催化脱羟甲基化平台。通过配体到金属的电荷转移催化，醇官能团已可靠地转移到亲核自由基中，同时失去一分子甲醛。有趣的是，我们发现铈催化剂可以显着促进脱羟甲基化过程，并且碎片自由基的稳定作用也起着重要作用。这种操作简单的方案能够直接利用伯醇作为非常规烷基亲核试剂，用于自由基介导的 1,4-共轭加成与迈克尔受体。广泛的醇类，从简单的乙醇到复杂的核苷和类固醇，已成功应用于这种片段偶联转化。此外，该催化系统的模块化已在多种自由基介导的转化中得到证实，包括氢化、胺化、烯基化和氧化。

  An iron-catalyzed radical alkylazidation of electron-deficient alkenes is reported. Alkyl diacyl peroxides work as the alkyl source, and trimethylsilyl azide acts as the azido reservoir. This method features mild reaction conditions, wide substrate scope, and good functional group tolerance, providing a range of α-azido esters, an α-azido ketone, and an α-azido cyanide in high yields. These azides
