A rhodium-catalyzed direct insertion of ethylene into a relatively unstrained carbon-carbon bond in 1-indanones is reported, which provides a two-carbon ring-expansion strategy for preparing seven-membered cyclic ketones. As many 1-indanones are commercially available and ethylene is inexpensive, this strategy simplifies synthesis of benzocycloheptenones that are valuable synthetic intermediates for

Discovery and Optimization of 1-Phenoxy-2-aminoindanes as Potent, Selective, and Orally Bioavailable Inhibitors of the Na<sup>+</sup>/H<sup>+</sup> Exchanger Type 3 (NHE3)
The design, synthesis, and structure–activity relationship of 1-phenoxy-2-aminoindanes as inhibitors of the Na+/H+ exchanger type 3 (NHE3) are described based on a hit from high-throughput screening (HTS). The chemical optimization resulted in the discovery of potent, selective, and orally bioavailable NHE3 inhibitors with 13d as best compound, showing high in vitro permeability and lacking CYP2D6
基于高通量筛选(HTS)的命中,描述了作为3 + Na + / H +交换剂(NHE3)抑制剂的1-苯氧基-2-氨基茚满的设计,合成及其构效关系。化学最优化导致发现了以13d为最佳化合物的有效,选择性和口服生物利用的NHE3抑制剂,显示出较高的体外通透性和缺乏CYP2D6抑制作用作为主要优化参数。将1-苯氧基-2-氨基茚满对准13d的X射线结构然后为NHE3抑制捕获指南提供了3D-QSAR模型以进行优化。这些模型显示出良好的相关系数,并可以进行活性估算。在计算机中针对Caco-2渗透性和CYP2D6抑制作用的ADMET模型也已成功应用于该系列。此外,对接CYP2D6 X射线结构为3D-QSAR模型提供了可靠的对齐方式。最终,重命名为SAR197的13d在体外和体内药代动力学(PK)和药理研究中进行了表征,以揭示其减少阻塞性睡眠呼吸暂停的潜力。
Catalytic Enantioselective Steglich-Type Rearrangement of Enol Lactones: Asymmetric Synthesis of Spirocyclic 1,3-Diketones
An example of asymmetric Steglich-type rearrangement of enol lactones is reported. This highly enantioselective acyl transfer reaction is catalyzed by chiral isothiourea at ambient temperature and provides a useful synthetic approach to access enantioenriched spirotricyclic β,β′-diketones from a broad range of indanone or tetralone-derived lactones. Preliminary mechanistic studies suggest the initial
