Two novel daidzein[1,3] oxazine derivatives were synthesized by a one-pot approach using daidzein, n-butyl amine and 37% aqueous solution of formaldehyde as the raw materials under ultrasonic radiation. The 1H and 13C NMR chemical shifts of the title compounds were assigned by two-dimensional NMR techniques, including DEPT, 1H-1H COSY, 1H-13C HSQC and 1H-13C HMBC. The reactive sites in daidzein were determined.
