Syntheses of Ammonium Compounds Containing Diphenyl Ether Nucleus

Syntheses and Applications of (Thio)Urea-Containing Chiral Quaternary Ammonium Salt Catalysts

We herein report our efforts to obtain a new class of systematically modified bifunctional (thio)urea-containing quaternary ammonium salts based on easily obtainable chiral backbones. Among the different classes of catalysts that were successfully synthesized, those based on trans-1,2-cyclohexane diamine were found to be the most powerful for the asymmetric α-fluorination of β-keto esters. Sele...

Syntheses and Structures of Three Mononuclear Coordination Compounds Containing Six- and Seven-Coordinated Manganese(II) Ions

The reactions o f M n(CF3COO)2 (1) with N,N,N',N'-tetramethylethylenediamine (tmen), 2,2'-bipyridine (bipy) and triethanolamine (tea) yield three new mononuclear coordination compounds: rra«5-[Mn(tmen)2(CF3COO)2] (2), cw-[Mn(bipy)2(C F3COO)2] (3), and [Mn(tea)2](CF3COO)2 (4). The X-ray structures o f the compounds 2, 3, and 4 are described. The seven-coordination o f the manganese(II) ion in 4,...

Synthesis and antitubercular activity of heterocycle substituted diphenyl ether derivatives.

Despite being an ancient disease, tuberculosis (TB) remains the leading single-agent infectious disease killer in the world. The emerging serious problem of TB control and clinical management prompted us to synthesize a novel series of heterocyclic substituted diphenyl ether derivatives and determine their activity against the H37Rv strain of Mycobacterium. All ten compounds inhibited the growt...
