  • Method for synthesizing artepillin C and intermediate compound thereof
    Patent number: 11739044
    Abstract: The present invention relates to a method for synthesizing artepillin C and a synthetic method for synthesizing an intermediate compound for use in preparing artepillin C. The structural formula of artepillin C is shown in the following formula (IV), and the intermediate compound is shown in the following formula (II). The synthesis method includes the following steps: a first reaction step: in the presence of a base initiator, a compound A shown in formula I and 3,3-dimethylallyl bromide are mixed, the reaction continues for a first reaction time and is stopped to generate an intermediate of artepillin C shown in formula II; and a second reaction step: the intermediate of artepillin C is dissolved in an aqueous alcohol solution and then mixed with an alkali metal salt, and the reaction continues for a second reaction time to generate artepillin C.
