Antimycobacterial compounds. New pyrrole derivatives of BM212
摘要:
We have identified BM212 as a lead compound among a series of pyrrole derivatives with good in vitro activity against mycobacteria and candidae. First studies led us to synthesize some pyrrole compounds in which the thiomorpholine fragment was present. Some compounds revealed very active and these findings prompted us to prepare new pyrrole derivatives 2-15 in the hope of increasing the activity. The microbiological data showed interesting in vitro activity against Mycobacterium tuberculosis and atypical mycobacteria. (C) 2004 Elsevier Ltd. All rights reserved.
Indium-mediated one-pot pyrrole synthesis from nitrobenzenes and 1,4-diketones
摘要:
One-pot reduction-triggered heterocyclizations of nitrobenzene derivatives with 1,4-diketones were investigated. In the presence of indium/AcOH in toluene at 80 degrees C, reaction of nitrobenzenes with 2,5-hexadione produced moderate to excellent yields (40-98%) of the corresponding pyrroles within 1.5-24 h depending on the substituents of the starting materials. Similarly, the reaction of nitrobenzenes with 1-phenyl-1,4-pantanedione in the presence of indium/AcOH in toluene at reflux afforded the corresponding pyrroles within 0.5-24 h with 60-98% yields.
