Versatile Synthetic Route for Resveratrol Modification via Amine Functionalization

Resveratrol derivatives containing a primary amine functional group were synthesized by an introduction of N-Boc-bromoethylamine to resveratrol using Williamson ether synthesis and subsequent deprotection of the Boc group with trifluoroacetic acid. After conjugation of fluorescent NBD-F or rhodamine B with isothiocyanate (Rhd B-ITC) using the amine group, resveratrols modified with NBD or Rhd B (Resveratrol-NBD and Resveratrol-Rhd B,...
