Technical field
The invention belongs to organic compound synthesis and applied technical fields, and in particular to a kind of 3- (benzenesulfonylmethyl) imidazoles
And the preparation method of heterocycle compound.
Background technology
Pyridine-imidazole is a kind of extremely important and common nitrogen heterocyclic(Comprehensive
Heterocyclic Chemistry III).Its derivative has good bioactivity:For example, antiviral, antiulcer and anti-
Bacterium property(J. Med. Chem. 2015, 58, 8529; Bioorg. Med. Chem. Lett. 2013, 23, 4996;
J. Med. Chem. 2015, 58, 9238; Bioorg. Med. Chem. 2011, 19, 4227; ACS Med.
Chem. Lett. 2013, 4, 675; J. Med. Chem. 1999, 42, 50).Wherein there are a few class drugs to succeed
Listing, such as anxiolytic drugs Alpidem(Alpidem), Saripidem(SariPidem), arcotic Necopidem(How
It can pyrrole denier)With hypnotic sedative agent Zolpidem(Zolpidem)Deng(J. Med. Chem. 2008, 51, 7243; Exp.
Ther. 2001, 299, 793; J. Behav. Pharmacol. 1995, 6, 116).Related pyridine-imidazole at present
The research for closing the function dough reaction of object and imidazoheterocycles class compound is gradually improved, but about the reaction of its sulfonymethylization
Research but has not been reported.
Toluenesulfomethyl isocyanide is widely used general in organic synthesis, utilizes its high activity and sulfonyl group
Easy leaving away property(Angew. Chem., Int. Ed. 2010, 49, 9094, Chem. Rev. 2010, 110, 5235,
Chem. Rev. 2015, 115, 2698), synthesized the azepines such as a series of heterocyclic compound, such as pyrroles, oxazoles, imidazoles
Cycle compound(Chem. Commun. 2014, 50, 11837, Chem. Eur. J. 2015, 21, 18949, Org.
Lett. 2014, 16, 4004, Adv. Synth. Catal. 2014, 356, 2974).This reaction is realized to toluene
Another reactive mode of sulfonymethyl isonitrile realizes sulfonymethylization using simple reaction system and reacts.
Invention content
The object of the present invention is to provide a kind of synthesis of 3- (benzenesulfonylmethyl) imidazoheterocycles class compound and preparation sides
Method, this method is simple and practicable, of low cost and be easy to purify.
To achieve the above object, the present invention uses following technical scheme:
A kind of 3- (benzenesulfonylmethyl) imidazoheterocycles class compound, general structure are:
Wherein X=C, O or S;N=0 or 1;R1For hydrogen, alkyl, alkoxy or halogen;Het is thiazoles, Thiazoling type, benzene
And thiazoles, quinolines Huo oxazole class heterocycles.
The preparation method of described 3- (benzenesulfonylmethyl) the imidazoheterocycles class compound, includes the following steps:In argon gas
Under environment, imidazoheterocycles class compound and benzenesulfonylmethyl isonitrile analog derivative are added in reaction tube, ferric trichloride is added,
Then green solvent is added, is reacted 18 ~ 48 hours at 80 ~ 120 DEG C;After reaction extraction, chromatographic isolation, be dried to obtain target
Product, reaction equation are as follows:
;
The general formula of the imidazoheterocycles class compound is:
The general structure of benzenesulfonylmethyl isonitrile analog derivative is:
Wherein X=C, O or S;n=0、1;R1For hydrogen, alkyl, alkoxy or halogen;Het is thiazoles, Thiazoling type, benzo
Thiazoles, quinolines Huo oxazole class heterocycles.
The amount ratio of the imidazoheterocycles class compound and the substance of benzenesulfonylmethyl isonitrile analog derivative is 1:2 or 1:3.
The dosage of the ferric trichloride is 0.1 ~ 0.3 times of the amount of the substance of imidazoheterocycles class compound.
The green solvent is water and polyethylene glycol 400 by volume 0 ~ 10:10 ~ 0 are mixed, with 0.1mmol miaows
On the basis of the amount of the substance of azoles and heterocycle compound, the dosage of the green solvent is 2mL.
