The invention discloses a novel total synthesis method of racemic tetrandrine, and belongs to the technical field of pharmaceutical chemical synthesis. 5-bromovanillin and 4-hydroxyphenylacetic acid which are low in price and easy to obtain are respectively used as starting materials to synthesize a compound 10, the compound 10 is used for synthesizing a compound 12 and a compound 14 through a simple route, and the two compounds are subjected to intermolecular and intramolecular Ullmann reaction to synthesize the racemic tetrandrine A. The key intermediates 12 and 14 are synthesized through the compound 10, the synthesis efficiency is greatly improved, the raw materials are utilized to the maximum extent, and the method is a racemic tetrandrine total synthesis route which is simplest in operation and lowest in cost so far.
