Abstract
A process for the preparation of cyclohexanol derivatives of formula (I) by reacting a compound of formula (II) with a compound of formula (III) in the presence of a base catalyst of formula (IV) or (V). In the above formula, R1-R9, A, B, X and p have tghe meanings given in the specification.
Description
FIELD OF THE INVENTION
The present invention relates to prepare cyclohexanol derivative such as 1-[cyano group (4-p-methoxy-phenyl) methyl] method of hexalin.
Background of related
Cyclohexanol derivative such as 1-[cyano group (4-p-methoxy-phenyl) methyl] hexalin is the intermediate that is used to prepare compound such as Wen Lafa star (thymoleptic), and the latter is by suppressing release neurotransmitters again, and norepinephrine and thrombotonin have antidepressant effect.As USP 4,535,186 is described, and cyclohexanol derivative can be by naphthenone or the rare ketone of ring-type and suitably (facing position or contraposition) benzyl cyanide anionic reactive preparation of replacement.
USP 4,535, and 186 described preparation methods comprise use organo-metallic alkali such as n-Butyl Lithium, so that the benzyl cyanide negatively charged ion in the induced reaction.Organo-metallic alkali is very expensive, must be lower than under-50 ℃ at least to use with the reactant equivalent, feature be in air to water sensitive, the danger of catching fire and explode is arranged, and productive rate is lower than 50%, so organo-metallic alkali is unpractiaca for plant-scale synthesizing.
USP 5,043, and 466 disclose the method for using organo-metallic alkali such as diisopropylamine lithium to prepare cyclohexanol derivative, with following reaction mechanism explanation.USP 5,043, and 466 method changes the ratio of mixture of varsol, attempt improves temperature of reaction and improves productive rate, but still has the problem of alkali diisopropylamine lithium, for plant-scale synthetic be unpractiaca, also be because too expensive, must handle and have the danger of catching fire and exploding.
The open № 1225356 (CN 1225356A) of Chinese patent discloses use alkali such as sodium methylate, sodium ethylate, sodium hydride, sodium amide prepares the method for cyclohexanol derivative, so that improve temperature of reaction to 0-5 ℃ of scope, but the quantity that is to use alkali at least with the reactant equivalent because their easy firings and blast also are dangerous.
Above-mentioned known method comprises two steps, even benzyl cyanide and alkali reaction produce negatively charged ion, and with negatively charged ion and ketone compound coupling, the reaction that particularly produces the negatively charged ion step has some difficulty, as the terminal point of definite this step and the anionic quantitative analysis of generation.These problems cause the variation of coupling step productive rate, therefore also are difficult to industrial production.
The general introduction of invention
The present invention relates to prepare the method for cyclohexanol derivative, this method has overcome the problem and the shortcoming of common process basically.
The purpose of this invention is to provide the method by benzyl cyanide and pimelinketone prepared in reaction cyclohexanol derivative, this method is economical, and rational output is arranged.
Another object of the present invention provides the method for preparing cyclohexanol derivative, and this method safety is favourable to environment, the danger of not catching fire and exploding, and because reactant is blended in the reaction entirely, simpler than the synthetic method of routine.
One aspect of the present invention is the method for the cyclohexanol derivative of preparation formula I:

The non-organo-metallic alkali that the present invention uses comprises amidine or the guanidine that formula IV or formula V represent, the example of non-organo-metallic alkali more particularly of the present invention comprises amidine for example 1,8-diazabicyclo [5,4,0] 11-7-alkene (DBU) and 1,5-diazabicyclo [4,3,0] ninth of the ten Heavenly Stems-5-alkene (DBN); Ring-type guanidine for example 1,5,7-three azabicyclos [4,4,0] 12-5-alkene (TBD) and 7-methyl isophthalic acid, 5,7-three azepines [4,4,0] 12-5-alkene (MTBD); Alkyl guanidine is tetramethyl guanidine (TMG) for example, tetrabutyl guanidine, pentamethyl-guanidine, five butyl guanidines and N '-butyl-N ", N " dicyclohexyl guanidine.Alkaline catalysts of the present invention can be a homogeneous catalyst, or go up the organic amine alkali that fixed contains amidine or guanidine radicals at polymer support (as polystyrene) or inorganic carrier (as silicon-dioxide), non-organo-metallic alkali of the present invention is select from the above-mentioned alkali of mentioning a kind of at least.
The quantity of the non-organo-metallic alkali that uses does not have special restriction, can be that about 0.0001-about 2 works as weight range for 1 normal formula II compound, and more preferably from about 0.005-0.5 works as weight range.Reaction of the present invention can successfully only use the alkaline catalysts of catalytic amount to finish, and this is favourable.
Whether the present invention can randomly not with an organic solvent not be included in the hydro carbons or the ether solvent that use in the conventional synthetic method, with an organic solvent synthesize, determine by those skilled in the art arbitrarily, but usually preferably not with an organic solvent.
Prepare 1-[cyano group (4-p-methoxy-phenyl) methyl that cyclohexanol derivative is represented suc as formula I according to the inventive method] hexalin, preferably about-20 to the 80 ℃ of scopes of temperature of reaction, more preferably from about 10-30 ℃, method of the present invention even can carry out in room temperature, this is favourable.
The invention provides at non-organo-metallic amine alkali (DBU for example, DBN, TBN, MTBD, TMG or N '-butyl-N ", N " and the dicyclohexyl guanidine) exist down, the method of right-benzyl cyanide and pimelinketone prepared in reaction cyclohexanol derivative by suitable replacement, shown in reaction mechanism I:
In above-mentioned reaction, R
6-R
9With the definition of p with above-mentioned definition, work as R
9When being alkyl, introduce by alkylation.
At 1-[cyano group (4-p-methoxy-phenyl) methyl represented suc as formula I of preparation] in the hexalin, non-organo-metallic alkali such as DBU as amine alkali, DBN, TBD, MTBD, TMG or N '-butyl-N ", N " dicyclohexyl guanidine is used for replacing organo-metallic alkali such as n-Butyl Lithium or the diisopropylamine lithium in the ordinary method, induces to produce the benzyl cyanide negatively charged ion.Using non-organo-metallic alkali with few relatively quantity is cheap relatively, for the less sensitivity of hydrolysis, can at room temperature operate, the danger of not catching fire and exploding, output is also better, is safety and simple industrial method, and the present invention simultaneously only needs the non-organo-metallic alkali of catalytic amount, can produce high purity, the cyclohexanol derivative of high yield.
Because not with an organic solvent, the present invention is simpler and favourable to environment, does not produce the organo-metallic by product.
