Benzopyran type cosmetic auxiliary material with anti-oxidization effect and preparation method thereof

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.

With eliminating free radical effect of the benzopyran-containing cosmetic auxiliary material and its preparation method (by machine translation)

Design and synthesis of novel fused heterocycles using 4-chromanone as synthon

A new series of heterocyclic systems, including azole, azolopyrimidine, and pyridopyrimidine derivatives, attached to 2H-chromene scaffold, was prepared by a convenient procedure through the reactions of (E)-2-dimethylamino-methylene chromanone with diffe

Synthesis and pharmacological profile of novel N-substituted N-[5H-[1]benzopyrano[4,3-d]pyrimidin-2-yl]-N-methylglycinamides

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.
