Under ultrasound irradiation, two new substituted aminomethyl derivatives of sinomenine 1a and 1b were synthesized at C-1 in A-ring through Mannich reaction. Furthermore, eight new substituted aminomethyl derivatives 2a2h have been prepared by the amine exchange reaction of the compound 1a with aromatic amines or morpholine. The structures of the new compounds have been characterized by IR, MS, 1H NMR and NOE spectra.

Key words: Mannich reaction, amine exchange reaction, sinomenine
