Description
Field that the present invention belongs to:
The present invention relates to chemical synthesis process suc as formula Gastrodine shown in (I) and similar phenol glucoside thereof.
Glycosyl is glucoside unit part partly
Formula (I)
Wherein, but glycosyl part monose, disaccharide, trisaccharide etc., monose can be five-carbon sugar, hexose or substituted monosaccharide, for example: ribose, ribodesose, wood sugar, pectinose, glucose, allose, seminose, semi-lactosi, glucosamine, lactose, maltose, raffinose or the like.But R1 C1～C6 alkyl alcohol or aldehyde, hydrogen atom can be at the ortho positions, a position, contraposition.But R2 C1～C6 alkyl, C1～C6 haloalkyl, C3～C6 cycloalkyl, aryl, hydrogen atom, amino, nitro, substituted-amino, halogen, hydroxyl can be at the ortho positions, a position, contraposition.The glycoside bond that generates can be α type glycoside bond or β type glycoside bond.
Background technology:
There are numerous small molecules phenol glycoside compounds with specific physiologically active in occurring in nature, for example: salicyl alcohol glucoside, small molecules phenol glycoside compound such as thizoma curculiginis glucoside, salicin benzoate, ursin, Gastrodine, Hilieidum, Arctiin, Phillyrin, be widely used in the pharmaceutical preparation that is used for health care of body or treatment disease that the people of other countries use, wherein, there is chemical compound lot to be considered to the main component or the effective constituent of these pharmaceutical preparations, caused correlative study personnel's concern.Because this kind compound content is lower in the natural product, generally speaking, content is lower than one of percentage, and directly extraction cost is very high from natural product, people expect to rely on the method for chemosynthesis, obtain a large amount of inexpensive small molecules phenol glycoside compounds for human used.
The chemical synthesis process of glycoside compound started from the beginning of last century, form glycosyl halides activatory method very important effect is arranged on the carbohydrate chemistry development history, foremost reaction has Koenigs-Knorr reaction [Koenigs, W.And Knorr, E. (1901), Ber.Dtsch.Chem.Ges., 34,957], generally all need to add heavy metal silver or mercury salt etc. in this type of reaction.Other method; for example; form glycosyl trichloroacetamide activation method (trichloroacetimidate Method) [Schmidt; R.R.and Kinzy; W. (1994) .Adv.Carbohydr.Chem.Biochem.; 50; 21], form glycosyl sulphur and replace (thioglycoside), glycosyl selenium replaces [Garegg such as (selenoglycoside) activation method; P.J. (1997) .Adv.Carbohydr.Chem.Biochem.; 52,179.Witczak, Z.J.and Czernecki; S. (1998) .Adv.Carbohydr.Chem.Biochem.; 53,143.], need to use severe toxicity and expensive chemical reagent; only limit to the usefulness that the laboratory makes a search, be difficult to be used for large-scale production.
In recent decades, chemical synthesis process about this type of small molecules glucoside compound has many research reports, mainly contain: the 1. chemosynthesis [Zhou Jun etc. of Gastrodine, the chemical research II of rhizoma Gastrodiae " Gastrodine and analogue thereof synthetic " chemical journal vol.38, No.2, in April, 1980], the synthetic route of this compound, with diacetyl oxide under perchloric acid catalysis, generate five acetyl glucose with the glucose effect, with red phosphorus and bromine reaction, obtain the bromo acetyl glucosamine again, bromo acetyl glucosamine and p-Hydroxybenzaldehyde condensation, condensation product is through reduction, acetylize, saponification, steps such as recrystallization are finished the chemosynthesis of Gastrodine; 2. chemosynthesis [the Li Wen etc. of ursin, " Synthesis of Arbutin by Phase-transter Catalysis Method ", Zhengzhou Polytechnical Univ.'s journal, 1999 the 20th the 2nd phases of volume], the synthetic route of this compound, with diacetyl oxide under perchloric acid catalysis, generate five acetyl glucose with the glucose effect, again with red phosphorus and bromine reaction, obtaining the bromo acetyl glucosamine, is catalyzer with the Tetrabutyl amonium bromide, bromo acetyl glucosamine and the condensation of single acetyl Resorcinol in two-phase system (trichloromethane/water), condensation product obtains the final product ursin through steps such as saponification, recrystallizations; 3. the improvement of the chemosynthesis of rhodioloside [Li Guoqing etc., " rhodioloside synthetic method ", Chinese pharmaceutical chemistry magazine; Vol.6; No.2, Jun.1996], the synthetic route of this compound; raw material 4-benzyloxy phenylethyl alcohol is dissolved in methylene dichloride and the ether mixing solutions; feed nitrogen protection, add bromo acetyl glucosamine and silver carbonate, to reacting completely; condensation product obtains the final product rhodioloside through saponification, shortening.4. the chemosynthesis of Hyperoside is [with faithful and upright person etc., " study on the synthesis of Hyperoside ", Acta Pharmaceutica Sinica, 1994; 29 (11)]; this synthetic route is in the presence of pyridine; semi-lactosi and acetic anhydride, the thick liquid of generation is dissolved in glacial acetic acid, feeds dry hydrogen bromide; finish bromo-reaction; obtain α-D-acetyl bromide for semi-lactosi, in reaction flask, add 5 successively under stirring; 7; 3 ', 4 '-four benzoyl quercetins, α-D-acetyl bromide are for semi-lactosi, anhydrous pyridine, silver suboxide, and afterreaction was complete in 86 hours; separate the product that obtains; under nitrogen protection, refluxed hcl acidifying 20 minutes with methyl alcohol, potassium hydroxide; 50% ethyl alcohol recrystallization is finished the chemosynthesis of Hyperoside.
The chemosynthesis of Gastrodine comes from people such as late nineteen seventies Zhou Jun in last century and be separated to a new compound from the Chinese medicine rhizoma Gastrodiae, be accredited as 4-hydroxymethyl phenyl-β-D-glucopyanoside through structure, pharmaceutical research shows that this compound has calmness, soporific function, think the effective constituent of Chinese medicine rhizoma Gastrodiae, called after Gastrodine (gastrodin).People such as Zhou Jun in 1980 have finished the chemosynthesis [Zhou Jun etc. of Gastrodine, the chemical research II of rhizoma Gastrodiae " Gastrodine and analogue thereof synthetic " chemical journal vol.38, No.2, in April, 1980], in this synthetic route, use the bigger red phosphorus of toxicity, bromine in a large number, exist the serious three wastes to handle problems, production safety and environmental safety are all brought unfavorable factor, and total yield is lower, and production cost is higher.This synthetic route is still adopted by the synthetic main manufacturing enterprise of Gastrodine bulk drug of China so far.People such as Pang Qijie in 1984 propose [the people such as Pang Qijie that improves one's methods of Gastrodine synthesis technique, " improvement of Gastrodine synthetic method ", medicine industry, 1984,3:3～4], in people's such as Pang Qijie the method, still use red phosphorus and bromine, just change one step of potassium borohydride reduction into Raney nickel shortening, do not have bigger actual application value, but also face the problem of new introducing heavy metal.
Summary of the invention: at the deficiency of prior art existence; the present invention proposes the chemical synthesis process of a kind of preparation Gastrodine and analogous henolic glycoside formula (I) thereof; it finishes the hydroxyl protection of glycosyl and the bromo-reaction of hemiacetal hydroxyl with industrial raw acetic acid acid anhydride and the acetyl bromide or phosphorus tribromide or phosphorus pentabromide of being easy to get, solved use in the existing Gastrodine production of raw medicine that red phosphorus, bromine bring destroy problem to the injury of direct labor's body and mind with to the pollution of environment.
