Nine new resveratrol derivatives, having bromo, iodo, and fluoroethyl groups, were designed and synthesized. All compounds having free phenol groups showed good free radicalscavengingactivity. Among them, 2-bromoresveratrol 19 has a similar free radicalscavengingactivity to (+)-catechin.
Iodination of arene-containing natural products employing N-iodosuccinimide catalyzed by In(OTf)(3) at ambient temperature is reported as a versatile and mild method for natural product derivatization amenable to small scale. This process facilitates natural product derivatization of arene moieties for SAR studies, homo- and heterodimerization of natural products, and also conjugation with reporters such as biotin via subsequent metal-mediated coupling reactions.
