Abstract

Abstract An effective and regioselective synthesis of aminomethylated daidzein derivatives using a Mannich reaction of daidzein, formaldehyde with a variety of amines under ultrasound irradiation is described. The structures of the products were characterized by HRMS, 1H NMR, 13C NMR and 2D NMR spectra. Parallel reactions showed that ultrasound irradiation accelerated the reaction rate and improved the yields.
