Description
The present invention relates to be reflected at Al catalysts and have preparation γ down, the modification method of delta unsaturated ketone, especially methyl heptenone, geranyl acetone and farnesyl acetone or their dihydro derivative or geranyl geranyl acetone with Karol.
The chain lengthening that means vinyl carbinol or propargyl alcohol and acetylacetic ester or diketene of Karol reaction, and generate γ, delta unsaturated ketone.For example, this reaction is undertaken by following reaction scheme:
Thereby in committed step, the acetylacetic ester of new unsaturated alcohol, this ester at first are ketogenetic by vinyl carbinol or propargyl alcohol and acetylacetic ester or diene, are rearranged into beta-keto acid by Claisen rearrangement, then its automatic decarboxylation.Preliminary research about the Karol reaction is described among J.Am.Chem.Soc.65 (1943) 1992-1998.
From nineteen fifty for beginning, this reaction is used for the preparation of terpene in every way.For example as the required terpenes 2-methyl of the main precursor of vitamin A and vitamin-E-2-heptene-6-ketone, 6,10-dimethyl-5,9-11 carbon diene-ketone (geranyl acetone) and 6,10,14-trimethylammonium-5,9,13-15 carbon triolefin-2 ketone (farnesyl acetone) prepare with technical scale with the Karol reaction.
For example, GB 695 313 has just disclosed in gas phase in 300-600 ℃ and has used the Karol reaction that allyl group or crot(on)yl acetylacetic ester carry out.
US 2628250 has disclosed by 2-methyl-3-butene-2-pure and mild diketene and has prepared 2-methyl-2-heptene-6-ketone.
US 2660608 has pointed out by tetrahydrochysene nerolidol and diketene and has prepared the tetrahydrochysene farnesyl acetone.
As the Karol catalyst for reaction, be to utilize aluminium alkoxide by the method for US 2795617, especially molecular formula is Al (O-CH (CH
3)
2)
3Aluminum isopropylate, its consumption is 0.8-2.5mol% based on the alcohol that uses as raw material.
According to the method for GB 886 353, for Karol reaction, be to use aluminium complex with methyl ethyl diketone or acetylacetic ester, as three (acetopyruvic acid) aluminium, three (methyl-acetoacetic acid) aluminium or three (ethyl acetoacetic acid) aluminium as catalyzer.
Under the situation of the Karol reaction of formerly known acetylacetic ester and uncle's vinyl carbinol or propargyl alcohol, generally be to use methyl or ethyl ester as Acetacetic acid alkyl ester.The carbonic acid gas one that the lower boiling alcohol that discharges in the acetoacetylization of unsaturated alcohol (methyl alcohol or ethanol) forms with decarboxylation the time is distilled out when reacting.
It is satisfied fully that the productive rate that is reached in the Karol reaction of using methyl acetoacetate or methyl aceto acetate still can not make us for plant-scale application.This is because the at first used reaction times is longer and second because the following fact, promptly under this reaction conditions, the beta-unsaturated ketone that is generated is measured slightly and is hydrogenated to the alcohol that is difficult to remove, and has so just reduced productive rate.
Thereby an object of the present invention is to shorten in the catalytic Karol reaction of aluminium, thereby reaction times of delta unsaturated ketone and improve the possibility that continuous processing is operated by vinyl carbinol or propargyl alcohol and acetylacetic ester prepared in reaction γ.A further object of the invention is further to improve productive rate.
Now, make us finding uncannily, when acetylacetic ester with the tertiary alcohol, when substituting methyl acetoacetate (AME) or methyl aceto acetate as the trimethyl carbinol, tertiary amyl alcohol (2-methyl fourth-2-alcohol) or dimethyl propyl methyl alcohol (2-methylpent-2-alcohol), the Karol reaction more promptly proceeds to γ, delta unsaturated ketone, and have higher productive rate, promptly generate less by product.If the application high-grade, thereby more valuable unsaturated alcohol is when making initial compounds, these improvement are particularly importants.This is particularly useful for 3,7-dimethyl-1,6-octadiene-3-alcohol (linalool), 3,7,11-trimethylammonium-1,6,10-12 carbon triolefin-3-alcohol (nerolidol), 3,7,10-trimethylammonium-1,6-12 carbon diene-3-alcohol (dihydro linalool) and be particularly suitable for E, E-3,7,11,15-tetramethyl--1,6,10, the application of 14-six tetraenes-3-alcohol (E, E-geranyl linalool).
Although EP 376859 B1 disclose; if use the tertiary alcohol; as the ester of the trimethyl carbinol or tertiary amyl alcohol as acetylacetic ester; at nucleophile; in the acetoacetylization as alkanol, alkylamine or alkyl sulfhydryl and acetylacetic ester or derivatives thereof, also can obtain good productive rate, but the reaction of this and Karol is irrelevant; and relate to turn into the functionallization of usefulness by the acetoacetyl of lower molecular weight or polymeric nucleophile, lower molecular weight or polymeric nucleophile finally as coating to improve dyeing.
The present invention relates to the γ of general formula I, the preparation method of delta unsaturated ketone,
This method be by the vinyl carbinol of general formula I I or propargyl alcohol and Acetacetic acid alkyl ester in the Karol reaction of randomly improvement in the presence of Al catalysts in temperature 150-220 ℃ reaction, and distill simultaneously and remove the alkanol of generation,

R in the formula
2It is alkyl with 1-4 carbon atom.
Make us uncannily, utilize method of the present invention, just can obtain senior γ by simple method and continuous processing operation, delta unsaturated ketone, for plant-scale method, this is desirable especially, and its productive rate is the 92-96% of theoretical value, even one of used reactive component is inexcessive or only slightly excessive.In addition, a very big advantage is the space-time yield that method of the present invention can increase the previously known method.
For the reaction of formula (II) alcohol, method of the present invention is a particularly important, the R in the formula (II)
1It is the group of general formula I V
N is that the integer of 1-5 and X and Y or two are H or X is that methoxyl group and Y are H in the formula, or X and Y be the other key that carries between the carbon atom of X and Y together, as 3,7-dimethyl-1,6-octadiene-3-alcohol (linalool), 3,7-dimethyl-1-octene-3-alcohol, 3,7,11-trimethylammonium-1,6,10-12 carbon triolefin-3-alcohol (nerolidol), 3,7,11-trimethylammonium-1-dodecylene-3-alcohol, 3,7,11-trimethylammonium-1,6-12 carbon diene-3-alcohol (dihydro nerolidol) and 3,7,11,15-tetramethyl--1,6,10,14-(E, E) 16 carbon tetraene-3-alcohol (E, E-geranyl linalool).
The application of etheric acid tertiary butyl ester or etheric acid tert-pentyl ester has the advantage of the by product that reacts more rapidly and avoid following.The amount of used reactant is preferably so carried out, so that the mol ratio of the Acetacetic acid alkyl ester of the alcohol of general formula I I and general formula III is 0.8-1.2, and preferred 0.95-1.10.

Therefore the catalyzer of mentioning at first is rudimentary three aluminium alkoxides, as three aluminum methylates, three aluminum ethylates, aluminum isopropylate, three aluminium secondary butylates, with the methyl ethyl diketone acidifying thing of this three alkane aluminium and stoichiometric quantity, the compound that generates in the reaction of Acetacetic acid alkyl ester or propanedioic acid alkyl ester reaction dealcoholysis simultaneously and transesterify.Example is the triacetyl aluminum acetate, praseodynium acid aluminium, single acetyl acetate diethyl aluminium alcoholates, single acetyl acetate aluminum-diisopropoxide, diacetyl acetic acid list aluminum isopropylate.
Preferred three aluminium alkoxides, particularly aluminum isopropylate and three aluminium secondary butylates of using.Extremely preferred the utilization mixed the triacetyl aluminum acetate, it is produced by aluminium secondary butylate or aluminum isopropylate and methyl acetoacetate reaction cancellation 2-butanols or Virahol and methoxyl group and the 2-butanols that disengages or the transesterify of Virahol simultaneously, and wherein the transesterify degree should be higher than 30%.
We think, three aryloxy aluminium are the aluminium salt of aromatic hydroxy compound, also can promptly be had the alkyl and the alkoxyl group of 1-4 carbon atom by low alkyl group or alkoxyl group as triphenol aluminium, three cresols aluminium, three xylenol aluminium, three naphthols aluminium, their aryl, hydroxyl or phenyl replace.Particularly advantageous in the middle of them is to use more wield triphenol aluminium.
It is favourable using the solution of liquid catalyst or solid catalyst and these catalyzer are added in the reaction vessel with liquid form.For example, can use like this three aluminium alkoxides that are dissolved in Acetacetic acid alkyl ester or be dissolved in Acetacetic acid alkyl ester and the mixture of the alcohol of a kind of general formula I I in three aluminium alkoxides.
The consumption of aluminum compound generally is that its concentration is not less than the aluminium of 0.05% weight and is reacting the aluminium that is no more than 6% weight when beginning in reaction mixture.Based on the Acetacetic acid alkyl ester of desire reaction, need the aluminum compound of 0.5-5mol% usually.For the aluminum isopropylate and the above-mentioned mixing triacetyl aluminum acetate that is made by aluminium secondary butylate and methyl acetoacetate of preferred use, based on desire reaction Acetacetic acid alkyl ester, for example consumption is about 1-3mol%.
When using boiling point to be lower than the vinyl carbinol of 120 ℃ formula II, during as 2-methyl-3-butene-2-alcohol, be particularly advantageous if Karol is reflected in the gamma lactone as the cyclic carbonate of the general formula VI of solvent or formula VII,
