Pulvinone and several 3-fluoro-4-morpholino substituted pulvinone derivatives were synthesized in five steps from a common precursor, phenyl acetic acid. Most of synthetic morpholine substituted pulvinones showed inhibitory activity against Esherichia coli. For the first time, the inhibition of pulvinone and itsderivatives against Gram-negative bacteria was reported.
The Suzuki-Miyaura coupling reactions of 3-bromo-2(5H)-furanones with a variety of arylboronic acids, promoted by microwave heating, efficiently generate 3-aryl-2(5H)-furan ones. This remarkably rapid process serves as the foundation for a simple method to rapidly construct 3-aryl-2(5H)-furanone libraries. (c) 2006 Elsevier Ltd. All rights reserved.
