Abstract
The invention relates to a compound for sugar saccharide recognition, in particular to a method for preparing a borate compound. A compound 1 passes BOC protection, and then is condensed with a compound 3 to obtain a compound 4, the reaction process is very clean, the polarity of the compounds is almost not dissolved in water, and the yield is high; the BOC is removed through hydrochloric acid methanol, and the purity and yield of an obtained compound 5 are very high. Therefore, the problem about purifying of the compound 5 is solved. A compound 6 is protected through trifluoromethylsulfonyl, then sulfonyl chloride is prepared, and the yield and purity are greatly improved. The purity of a compound 8 can be improved to 90% simply through washing, and the compound 8 is also very stable and not likely to go bad, and is easy to produce. In the reaction of synthesizing a compound 10, due to the fact that the purity of sulfonyl chloride is very high, purifying of a compound 9 is very convenient, and the yield is high. Finally, the pure compound 10 can be directly obtained without purifying trifluoromethylsulfonyl during removal.
Description
Technical field
The present invention relates to a kind of compound for carbohydrate identification, especially a kind of preparation method of borate compound.
Background technology
In US Patent No. 5631364, synthetic route is:
The shortcoming that existence three is fatal in above-mentioned operational path:
One, in the reaction of the compound 5 of synthesis, have a lot of by product polarity very large, and compound 5 is very easily water-soluble, organic solvent extraction not out, causes the low purification difficult of yield like this.
Two, compound 6 synthetic compound 11 time reaction very assorted, can not purifying, during purifying compound 11 apt to deteriorate thus can only directly down single step reaction use.
Three, cause compound 10 very difficult when synthetic compound 10 because compound 11 is impure, purify anti-phase purifying convenient to both ability convenient to both with normal-phase chromatography passable, yield is very low less than 1%.
Therefore, find simple to operate, security is high, side reaction is few, transformation efficiency is high, yield is high, environmental pollution is little, production cost is low, be suitable for the preparation method of suitability for industrialized production compound 10 is the technical problems being badly in need of at present solving.
Summary of the invention
Side reaction is caused to increase because synthesize direct polycondensation in the reaction of 5 in US Patent No. 5631364 like this because two amino can react, and product is soluble in water is not dissolved in organic solvent very much, so just can not wash, direct post product polarity of crossing easily is adsorbed by pillar greatly, causes productive rate and purity to be all difficult to improve.So in the present invention by two of compound 1 amino with BOC protection, carry out condensation reaction reaction and be totally easy to purification yield and also greatly improve.
Very assorted owing to there being the naked leakage conductance of ammonia hydrogen to cause reaction in compound 6 in synthetic compound 11 in US Patent No. 5631364, and the SULPHURYL CHLORIDE instability made can not be washed and can not be crossed column purification, synthetic compound 10 can only be directly used in, cause the purification difficult yield of compound 10 very low.Protected by fluoroform acyl group by compound 6 in the present invention, then do SULPHURYL CHLORIDE, yield purity all improves a lot, and just the purity of compound 8 can be brought up to 90% by washing, and compound 8 also very stable being not easy rotten be easy to production.In addition, the purity of the present invention due to yellow acyl chlorides in the reaction of synthetic compound 10 is very high, and just very convenient yield is also high for the purifying of such compound 9, and most rear dragging fluoroform acyl group directly need not can obtain sterling compound 10 by purifying.
A preparation method for borate compound, comprises the following steps:
(1) compound 1 obtains compound 2 by BOC protection;
(2) compound 2 and compound 3 condensation obtain compound 4;
(3) compound 4 drags BOC by hydrochloric acid methanol, obtains compound 5;
(4) compound 6 obtains compound 7 by the protection of fluoroform acyl group;
(5) compound 7 obtains compound 8 by SULPHURYL CHLORIDE;
(6) compound 5 and compound 8 synthetic compound 9;
(7) compound 9 obtains compound 10 by dragging fluoroform acyl group.
Preferably, in step (1), compound 1 is dissolved in methyl alcohol, drips the dioxane solution of BOC2O, keep temperature lower than 10 DEG C, then stirred overnight at room temperature, reaction solution is concentrated into dry adding water, with dichloromethane extraction at least 3 times, merge organic phase, be concentrated into and dryly obtain compound 2.
Preferably, in step (2), compound 3 is dissolved in DMF, is cooled to 0 DEG C to add HOBT, then the DMF solution of DCC is dripped, keep temperature lower than 10 DEG C, then stirred overnight at room temperature, filtering reacting liquid, keep temperature lower than 10 DEG C in filtrate added drop-wise to the pyridine solution of compound 2, then stirred overnight at room temperature, reaction solution is concentrated into dry, crosses post and obtains compound 4.
Preferably, in step (3), be dissolved in methyl alcohol by compound 4, be cooled to 0 DEG C to drip HCl methanol solution, keep temperature lower than 10 DEG C, then stirred overnight at room temperature, reaction solution is concentrated into and obtains compound 5.
Preferably, in step (4), be dissolved in trifluoroacetic anhydride by compound 6, Heating temperature was to 50 DEG C of reactions 8 hours, and reaction solution is concentrated into dry, obtains compound 7.
Preferably, in step (5), compound 7 is dissolved in methylene dichloride and DMF, 0 DEG C is cooled to drip oxalyl chloride, keep temperature lower than 10 DEG C, then stirred overnight at room temperature, reaction solution is concentrated into dry, then add methylene dichloride dissolve and wash with frozen water, organic phase is concentrated obtains compound 8.
Preferably, in step (6), compound 5 is dissolved in methyl alcohol and DMF, and is cooled to 0 DEG C, adds sodium bicarbonate aqueous solution; Then drip the acetonitrile solution of compound 8, keep temperature lower than 10 DEG C, then stirred overnight at room temperature; The concentrated post of reaction solution obtains the crude product of compound 8, then obtains compound 9 after reversed-phase column.
Preferably, in step (7), compound 9 is dissolved in methyl alcohol, adds salt of wormwood, stirred overnight at room temperature, and then reacting liquid filtering obtains compound 10 at mistake reversed-phase column.
