Abstract
A process for preparing levo-salbutamol includes such steps as asymmetrical dihydroxylation reaction of properly substituted and protected styrene derivative, converting the class-one hydroxy of asymmetrical glycol to proper dessociative group, replacing the dessociative group by tert-butylamine, and removing protecting group.
Description
Technical field the present invention relates to a kind of novel preparation process of Levalbuterol, and the structure of Levalbuterol as shown in Figure 3.
Synthesis step of the present invention comprises: (1) suitably replaces and the asymmetric dihydroxy reaction of the styrene derivatives protected; (2) the one-level hydroxyl with asymmetric ethylene glycol is transformed into suitable leavings group; (3) replace this leavings group with TERTIARY BUTYL AMINE, remove protecting group thereupon, promptly get Levalbuterol.
Background technology The present invention be more particularly directed to have the antasthmatic of significant curative effect effect---Levalbuterol.Modern age, experiment showed to have the drug molecule at optical activity center, and its single optical activity isomer has stronger activity and reduces side effect than raceme.
About the preparation of the optical activity isomer of theme of the present invention-phenyl amine alcohol, reported in literature is much about the part recrystallization method of synthetic intermediate or final product.For example, the preparation method of known optically pure chirality salbutamol of people and Fu Mateluo; Can often in building-up process, run into a lot of problems as the optically pure product of medicine yet will synthesize in this way, comprise the costliness of raw material reagent, the part recrystallization solvent reclaims repeatedly, a large amount of manpowers expend loss of yield 50%, the generation of the enantiomorph of non-expectation.
Salbutamol, its chemistry α by name-{ [(1, the 1-methylethyl) amine] methyl }-4 hydroxyls-1, the 3-xylyl alcohol is the beta-2 adrenoceptor excitomotor, as bronchodilator.It is at β
1Acceptor (being present in heart) and β
2Acceptor has high selectivity between (being present in bronchial tissue and other positions), because this reason, the salbutamol of therapeutic dose is wanted much less than many other beta-2-agonists Side effects of pharmaceutical drugs, and it is widely used for treating asthma.Salbutamol still be one efficiently domestic animal urge longly plain, be used for the raising of chicken at large at some national salbutamols in Europe.
As everyone knows, exist chiral centre in many medicines, the wherein a kind of enantiomorph in the raceme in therapeutic process often than another enantiomorph drug effect height.Data show that the drug effect of salbutamol levo form (R type) enantiomorph exceeds 80 times approximately than dextrorotatory form (S type) recently.(Hartley and Middlemis, J.Med.Chem.14,895-896,1971) are taken optically pure R type salbutamol and can be improved therapeutic index.All β
2In the receptor stimulant, have only levo form that the effect of beta receptor agonist is arranged.Salbutamol S type isomer does not have avidity to beta-2 adrenoceptor.Yet S type salbutamol has identical acute toxicity with the salbutamol of R type, and biological half-life longer than having of R type in human body of S type.S type salbutamol can cause the overreaction of segmental bronchus and uterine smooth muscle, is easy to enter in the fetus body by the placenta barrier film.Because of R type salbutamol sulfate has higher curative effect and less side effect, it is by food and drug administration (FDA) approval, as the new drug of treatment asthma.In addition R type salbutamol also developed into one efficiently domestic animal urge longly plain, avoided potential side effect and the drug residue relevant with S type salbutamol.
Article at least two, synthetic method is used to control the stereochemistry of salbutamol and relevant amine alcohol chiral centre.First kind is used at preparation pure salbutamol R type and the method for S type enantiomorph, the i.e. chiral separation method of synthetic intermediate or final product raceme mixture.(with reference to Bakale etc., Clinical Reviewin Allergy and Immmunology vol 14 pp 7-35,1996).Second method is to adopt asymmetric catalysis synthesis, from the chiral precurser synthesizing chiral compound.
One of method that chemistry splits is with chiral acid and racemic salbutamol, or its precursor form diastereoisomeric salt (USP 5,399,765; 5,545,745; Ferrayoli etc., Enantiomer vol 5 pp289-291,2000).With salt with pure recrystallization repeatedly after, the salbutamol (or precursor) of R or S type discharges from salt with alkali.Chiral acid can use (-)-two-(to toluyl)-L-tartrate, (+)-two-(to toluyl)-D-tartrate, (-)-two-benzoyl-L-tartrate, (+)-two-benzoyl-D-tartrate.The shortcoming of this method is: (1) poor efficiency, as, the salbutamol of R type and S type (or its precursor) is a racemic mixture, contains 50% R type isomer and 50% S type isomer, the maximum yield of R type isomer just 50%.And reality is more much smaller than 50%.(2) costliness, chiral acid as described above particularly is used for preparing (+)-two-(to toluyl)-D-tartrate of the salbutamol (or precursor) of R type, and (+)-two-benzoyl-D-tartrate is too expensive, and technology is not to gather very much effect.
In laboratory study, the chirality synthetic method of the steric isomer of at present the most successful salbutamol is to be based upon utilization homogeneous phase chirality organic boron as on the Stereoselective reduction technical foundation of catalyzer.(J.Org.Chem vol 60, pp 41-46,1995) racemic secondary alcohol obtains by an achirality reductive agent reduction precursor ketone (being connected to different groups on the carbonyl).When adding resembles the such catalyzer of the organic boron of chirality, the S type that obtains that often can highly selective or the alcohol of R type.But, this Stereoselective reduction method also is not applied in the production of R type salbutamol on a large scale, because chiral catalyst is too expensive.
So people need seek the synthetic method that obtains optically pure phenyl amine alcohol or its intermediate with the stereoselectivity chemical reaction.
The synthetic needs that obtain optically pure phenyl amine alcohol or its intermediate with the stereoselectivity chemical reaction have been satisfied in this invention of goal of the invention.
Purpose of the present invention just provides terrible synthetic method to optically pure phenyl amine alcohol or its intermediate, comprises following step:
(a) one is suitably replaced and the vinylbenzene of due care contains the two pure of a primary alconol and a secondary alcohol by what asymmetric dihydroxy was deformed into a chirality.
(b) primary alconol with ethylene glycol is transformed into a suitable leavings group,
(c) generate a chirality phenyl amine alcohol with suitably replacing and protecting primary amine to replace leavings group.Technical scheme method provided by the invention mainly is the preparation about the single optical isomer of a phenyl amine alcohol, and this compound is by a phenylglycol that suitably replaces, and promptly the precursor of phenyl amine alcohol obtains high optical activity.General method of the present invention is as follows:
(a) one is suitably replaced and the vinylbenzene of due care by becoming the ethylene glycol that contains a primary alconol and a secondary alcohol of a chirality.
(b) primary alconol with ethylene glycol is transformed into a suitable leavings group.
(c) primary amine with suitable substituting group and protection replaces chirality phenyl amine alcohol of leavings group generation.
For the purpose of the present invention, suitable substituting group and suitable technical term be meant occur in the literary composition can generate the useful final product and the substituting group that compound is with of intermediate thereof.To chirality phenyl amine alcohol; useful final product is the beta-2 adrenoceptor excitomotor of phenyl amine alcohols, comprises salbutamol, Fu Mateluo; the useful especially intermediate that special sieve of husky benzene, terbutaline etc. resemble these compounds comprises the chirality phenylglycol of corresponding protection.
So-called suitable protecting group is meant that a group is being used for protecting a special compound to be vulnerable to attack and the position of react with in indivedual reactions or reaction, this group can be removed under existing other group situations not destroying in the compound afterwards.The optimal protecting group of hydroxyl has similar groups such as ester, carbonic ether, carbamate, ketal.The best protection base of amido has acid amides, amino-carbon acid esters and relevant group.A large amount of suitable protecting groups and lose protective reaction description to some extent in " organic chemistry protecting group " accordingly.(JohnWiley and Sons; Inc., New York, 1991; ISBN0-471-62301-6) (" Greene ")) (GeorgThieme Verlag Stuttgart; New York, 1994) this book chapter 1 particularly, blocking group: summary 1-20 page or leaf; chapter 2, hydroxyl protecting group 21-94 page or leaf; chapter 3, glycerol protection base 95-117 page or leaf, chapter 4 carboxyl-protecting group 118-154 page or leaf, chapter 5 carbonyl-protection base 155-184 page or leaf.
So-called good leavings group is meant under the situation that does not influence other functional groups in the compound, is easy to be substituted by reaction immediately generate desired product.The corresponding leavings group of hydroxyl has tosic acid base, methylsulfonyl, trifluoroacetic acid base and relevant group.
In the present invention, suitably the vinylbenzene that replaces is made by corresponding phenyl aldehyde by the known method of author, and the multistep operation steps by subsequently makes target compound.For example as Fig. 1, among this figure, crucial asymmetric dihydroxy reagent is: the mixture for preparing R type ethylene glycol is the Tripotassium iron hexacyanide, salt of wormwood, four hydration potassium osmates, dihydro quinoline Ni Ding-2, the 3-dihydro naphthalene catalyzer (DHQD) of mixing
