Alcohols and ethers were identified as sustainable methine sources for synthesizing quinazolinone and benzimidazole derivatives using a combination of TsOH·H2O/O2 and appropriate bis-nucleophiles for the first time. Deuterium labeling studies clearly proved that the C2 hydrogen of the synthesized heterocycles came from the methine source. These unique reaction conditions were successfully applied to the synthesis of echinozolinone (2e′), 2f′ (a common precursor of rutaecarpine and (±) evodiamine), and dimedazole (6d). Notable features of this method include its low toxicity, use of commercial feedstocks as substrates, low cost, broad functional group tolerance and suitability for a wide range of bis-nucleophilic starting materials.

A series of 2-amino benzoic acid derivatives (1-28) were synthesized and evaluated for their in vitro antimicrobial activity against the panel of Gram positive, Gram negative bacterial and fungal strains. The results of antimicrobial studies indicated that, in general, the synthesized compounds were found to be bacteriostatic and fungistatic in action. QSAR studies performed by the development of one target and multi target models indicated that multi-target model was effective in describing the antimicrobial activity as well demonstrated the effect of structural parameters viz. LUMO, 3χv and W on antimicrobial activity of 2-amino benzoic acid derivatives. Springer Science+Business Media, LLC 2010.
