✦ Synopsis
Abstract
Chalcones, intermediates in flavonoid biosynthesis, can exhibit antibacterial, antiproliferative, and anti‐inflammatory properties. Chalcones contain two benzene rings and both hydroxylated and methoxylated analogs are frequently produced by hydroxylases and O‐methyltransferases in plant biosynthetic pathways. Assignments of NMR peaks in the spectra of hydroxylated and/or methoxylated chalcones can help in identifying novel chalcone derivatives isolated from natural sources by referencing these data against NMR spectra obtained from known chalcones. We report here the syntheses of 20 chalcones and complete assignments of ^1^H and ^13^C NMR spectra. Copyright © 2010 John Wiley & Sons, Ltd.
