A Practical Preparation of 7-Methoxy-3(2H)-Benzofuranone
摘要:
A practical new synthesis suitable for large-scale production of 7-methoxy-3(2H)-benzofuranone by conversion of commercially available 2-hydroxy-3-methoxybenzoic acid to 7-methoxy-3-acetoxybenzofuran followed by hydrolysis is described.

A new series of (Z)-2-(1-methyl-5-nitroimidazole-2-ylmethylene)-3(2H)-benzofuranones (11a-p) and (Z)-2-(1-methyl-4-nitroimidazole-5-ylmethylene)-3(2H)-benzofuranones (12a-m) were synthesized and assayed for their antibacterial activity against Gram-positive and Gram-negative bacteria. Most of the 5-nitroimidazole analogues (11a-p) showed a remarkable inhibition of a wide spectrum of Gram-positive bacteria (Staphylococcus aureus, Streptococcus epidermidis, MRSA, and Bacillus subtilis) and Gram-negative Klebsiella pneumoniae, whereas 4-nitroimidazole analogues (12a-m) were not effective against selected bacteria. The quantitative structure-activity relationship investigations were applied to find out the correlation between the experimentally evaluated activities with various parameters of the compounds studied. The QSAR models built in this work had reasonable predictive power and could be explained by the observed trends in activities. (C) 2007 Elsevier Ltd. All rights reserved.
