Description
(1) technical field
The present invention relates to a kind of Mechanochemical preparation of flavonoid compound.
(2) background technology
Flavonoid compound is the important natural product of a class, has anti-cardiovascular disease, anti-inflammatory, anti-liver virus, various active such as antibiotic.Flavonoid compound can directly obtain from food, also can extract from the plant of being rich in flavonoid compound, makes various protective foodss as foodstuff additive.The synthetic generally attention that is subjected to the chemist of flavonoid compound.
The existing quite long history of the chemosynthesis research of flavonoid compound, classical synthetic method mainly contains two kinds of routes, i.e. phenyl styryl ketone route and β-propanedione route.β-propanedione route is o-hydroxyacetophenone and aryl formyl chloride (or aryl formic acid or aryl formic anhydride) XianCheng's ester, and intramolecularly Claisen resets and generates β-propanedione intermediate again, and last cyclization generates flavonoid compound.Wherein ring-closure reaction is most important.
Acidization is often adopted in the cyclization of β-propanedione, promptly raw material in solvent with the acid reagent generation flavones that reacts.This method generally needs to carry out at reflux temperature, and the reaction times is longer.In recent years, the someone adopted I
2-DMSO, Co
III(salpr) (OH) or trifluoromethanesulfonic acid wait to synthesize flavones, also the someone adopts CuCl
2Or [EtNH
3] NO
3The synthetic flavones of auxiliary microwave method, but these methods still are in the research exploratory stage at present.
Mechanochemistry (mechnochemisty) also is called mechanical force and chemical, is to specialize in object in the effect of high energy mechanical power with bring out a subject that issues living physicochemical change, and be one of front subject of Green Chemistry.Solid-state chemical reaction under the mechanical force, the reaction system microenvironment is different from the solution, can form high local concentrations at reactive site, both improved speed of reaction, improve productive rate and selectivity again, also can make the separation purification of product become simple, reduced production cost simultaneously again.What is more important owing to there is not the intervention of solvent, can avoid in the reaction process solvent to the pollution of environment.Yet there are no the report that adopts the mechanochemistry method to prepare flavonoid compound.
Therefore, the ring-closure reaction of finishing β-propanedione with the mechanochemistry method prepares flavonoid compound, is the important breakthrough to traditional flavonoid compound synthetic method.
(3) summary of the invention
The technical problem to be solved in the present invention provide a kind of easy and simple to handle, production safety is reliable, the reaction times is short, reaction yield is high, production cost is low, do not have the preparation method of the flavonoid compound that the three wastes produce substantially.
The technical solution adopted in the present invention is:
A kind of structure is suc as formula the Mechanochemical preparation of the flavonoid compound shown in (II), described method comprises: with structure suc as formula the 1-shown in (I) (2 '-hydroxy phenyl)-3-aryl-1, the 3-propanedione is a raw material, with the hydrosulfate is catalyzer, with silica gel is grinding aid, ball-milling reaction in the closed ball milling jar; Reaction finishes the afterreaction mixture and obtains structure suc as formula the flavonoid compound shown in (II) after separation and purification.Reaction formula is as follows:
In formula (I), the formula (II), R

The present invention's suggestion usually reacts under the state of high speed ball milling, and the high speed ball milling of indication is often referred to rotating speed between 1290~2220rpm.
Hydrosulfate of the present invention can be selected from the combination of following one or more arbitrary proportions: sal enixum, sodium pyrosulfate, magnesium hydrogen sulfate, calcium bisulfate, aluminium hydrogen sulfate, hydrogen sulfate zinc, hydrogen sulfate iron; Contain or do not contain crystal water in the structural formula of described hydrosulfate.Further, described hydrosulfate is preferably the mixing of following one or more arbitrary proportions: sulfuric acid monohydrate hydrogen sodium, sal enixum, magnesium hydrogen sulfate.
Hydrosulfate of the present invention, 1-(2 '-hydroxy phenyl)-3-aryl-1, the ratio of the amount of substance that feeds intake of 3-propanedione compounds be recommended as 1: 3~and 1: 20, be preferably 1: 4~1: 10.
Described silica gel quality is 1-(2 '-hydroxy phenyl)-3-aryl-1, and 5~20 times of 3-propanedione compounds quality are preferably 5~8 times.
The described reaction times was generally 2~20 minutes, was preferably 5~10 minutes.
Described separation purification method carries out according to following steps: the solvent with heat washes complete reaction mixture, filters, and filtrate is steamed under boiling state and fallen partial solvent to saturated, is cooled to room temperature, separates out solid, and drying obtains flavonoid compound.
Described solvent is the combination of following one or more arbitrary proportions: ethanol, methyl alcohol, ethyl acetate, methylene dichloride, further, described solvent is for being ethanol.
Comparatively concrete, recommend described method to carry out: in ball grinder, to press hydrosulfate: 1-(2 '-hydroxy phenyl)-3-aryl-1 according to following steps, 3-propanedione compounds is 1: 4~10 to feed intake, and described hydrosulfate is the combination of one or more arbitrary proportions in sulfuric acid monohydrate hydrogen sodium, sal enixum, the magnesium hydrogen sulfate; Adding 1-(2 '-hydroxy phenyl)-3-aryl-1, the silica gel that 3-propanedione compounds quality is 5~8 times.To place ball mill in the ball grinder with the rotating speed ball-milling reaction of 1290~1920rpm 5~10 minutes.After reaction finishes, with hot ethanol complete reaction mixture is washed, filter, filtrate is steamed under boiling state and is fallen part ethanol to saturated, is cooled to room temperature, separates out solid, and drying obtains flavonoid compound.
Beneficial effect of the present invention is embodied in: (1) original method reaction generally all is to carry out in solvent, and the inventive method has been got rid of and easily environment produced the solvent that pollutes; (2) the inventive method need not to use strongly-acid reagent; (3) the inventive method has shortened the reaction times greatly; (4) the inventive method yield height not only, but also make reaction substrate select face to widen greatly, before having solved for the 1-of different substituents (2 '-hydroxy phenyl)-3-phenyl-1,3-propanedione derivative, yield changes problem greatly;
To sum up, the present invention has the reaction times weak point, reaction yield is generally higher, production safety is reliable, production cost is low, aftertreatment is simple and pollute advantages such as few, is a kind of preparation method with flavonoid compound of better popularizing application prospect.
