The disclosure provides compounds and pharmaceutical compositions of aryloxyacetylindoles compounds and analogs useful for treating chronic and acute bacterial infections. Certain of the compounds are compounds of general Formula (I) (I) or a pharmaceutically acceptable salt or prodrug thereof. Certain compounds of this disclosure are MvfR inhibitors. MvfR inhibitors reduce the formation of antibiotic tolerant bacterial strains and are useful for treating Gram-negative bacterial infections and reducing the virulence of Pseudomonas aeruginosa. Methods of treating bacterial infections in a subject, including Pseudomonas aeruginosa infections, are also provided by the disclosure.

strategies have been considered to achieve the first total synthesis of nhatrangins A and B. The first approach based on a cross metathesis (CM) reaction was unsuccessful. The second, which combined a highly stereoselective alkylation, a diastereoselective aldolization, and finally an esterification, furnished an advancedaldehydeintermediate bearing the three contiguous stereogenic centres and the expected
已经考虑了两种不同的策略来实现首次全合成 nhatrangins A 和 B。基于交叉复分解 (CM) 反应的第一种方法是不成功的。第二个结合了高度立体选择性烷基化、非对映选择性醛醇化和最后的酯化,提供了带有三个连续立体中心和预期侧链的高级醛中间体。

several steps to introduce alkynyl ester functionality, the stereoselective addition of a tributyltin cuprate followed by tributyltin–bromine exchange gave the required vinylic bromides. The palladium(0) catalysed couplings worked very well for enol esters containing thioether substituents and gave products with retention of the position and geometry of the trisubstituted double bond derived from the vinylic
