An efficient synthesis of aryloxyphenyl cyclopropyl methanones: a new class of anti-mycobacterial agents
摘要:
An efficient, high yield and one-pot synthesis of phenyl cyclopropyl methanones by reaction of different aryl alcohols with 4'-fluoro-4-chloro-butyrophenone in THF/DMF in the presence of NaH/TBAB is reported. Most of the methanones were further reduced to respective alcohols or methylenes. All the compounds were evaluated for their anti-tubercular activities against M. tuberculosis H37Rv in vitro displaying MICs ranging from 25 to 3.125 mu g/mL. The most active compounds showed activity against MDR strains and two of them (14 and 16) showed marginal enhancement of MST in mice. (c) 2005 Elsevier Ltd. All rights reserved.

A series of 1-[(4-benzyloxyphenyl)-but-3-enyl]-1H-azoles has been identified as potent antitubercular agents against Mycobacterium tuberculosis. Synthesis of compounds involved acid catalyzed ring-opening of cyclopropyl ring of phenyl cyclopropyl methanols followed by nucleophilic attack of the azoles on the carbocation intermediates. Several of the compounds 26, 34, and 36 exhibited significant antitubercular
