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.
A general procedure for the synthesis of methylthio-, methylseleno- and methyltelluro-substituted aromatic compounds

A one-pot procedure is described which allows the facile introduction of one or two methylchalcogeno groups into a variety of monobromo or dibromo aromatics. The bromo compounds were converted to their corresponding lithio derivatives by treatment with t-butyllithium in tetrahydrofuran at −78°C, and these derivatives were then treated, at ambient temperature with elemental sulfur, selenium, or tellurium
Synthesis of annulated dioxins as electron-rich donors for cation radical salts

The synthesis of a series of new alkoxylated linearly annulateddioxins is described together with their cyclic voltammetric behavior and some preliminary result on their ability to form cationradicalsalts. Of these dioxins, seven (8, 12, 19, 21, 27, 33, 34) are the first representatives of entirely new heterocyclic systems. Dioxins 8, 21, 22 and 27 gave good quality cationradicalsalts upon el
A new PtCl2/PtCl4-catalyzed hydroarylation/cycloisomerization cascade reaction leading to the formation of two aromatic or heteroaromatic rings in one step is reported. The strategy developed is exemplified by the synthesis of the 5,6-dihydrobenzo[c]phenanthrene and 6H-naphtho[2,1-c]chromene skeletons. Attempts to prepare [8]helicene-like molecules are also discussed.

3,6,8,11-Tetramethoxybenzo[j]fluoranthene can be made from 1,6-dimethoxynaphthalene in a one-pot ferric chloride oxidation/methanol reduction procedure. The reaction is tolerant of the presence of substituents in the 7-position of the naphthalene nucleus and provides a quick and easy route to these particular benzo[j]fluoranthenes. The reactions presumably proceed through initial formation of a bond
