-
Paragraph 0054-0056, (2019/07/01)
The invention discloses a benzopyran type cosmetic auxiliary material with an anti-oxidization effect and a preparation method thereof and belongs to the technical field of synthesis of functional organic molecules. The technical scheme provided by the invention has the essentials that the benzopyran type cosmetic auxiliary material has a structure shown as a formula: The formula is shown in the description. A benzopyran type compound with a novel structure is synthesized through a novel method; an anti-oxidization research is carried out and a human skin patch test is carried out to display that the compound has no bad influences on human skin under certain concentration, so that the compound is hopefully applied to cosmetics and is used as an anti-oxidization additive auxiliary material.

The title compounds were synthesized by cyclizing 3-dimethylaminomethylene-4-chromanone with creatine to give the acid 2 that was successively converted into the corresponding amides 3a-f via diphenylphosphorylazide and the relevant amines. The free acid 2 and some of 3a-f showed antiinflammatory, hypotensive and antiarrhythmic properties.
