Abstract
Sulphone as an important organic intermediate, widely found in drugs such as eletriptan, an anti-migraine drug, adroquinone, for the treatment of breast cancer, etaxib, for the treatment of osteoarthritis, and gamma-secretase inhibitors, drugs used for the prevention of alzheimer's disease, contain sulphone building blocks. The sulfone compounds have good antibacterial activity, so the sulfone compounds are also applied to organic pesticides, such as herbicide cafenstrole and insecticide oxycarboxin. In addition, in the aspect of novel functional materials, the poly diaryl sulfone molecules have special photophysical properties and also have wide application in light-emitting diode materials. The patent develops a simple, convenient and efficient method for synthesizing beta-ketone thiosulfone compounds by one-step reaction of double functionalization of arylformyl methylene dimethyl sulfur bromide and thiosulfonic acid ester, the method obtains products with moderate to good yield, and the method has wide substrate range, high functional group tolerance and good applicability.
Description
Technical Field
The patent relates to the research field of organic synthesis, pharmaceutical synthesis and organic chemical industry, in particular to a method for synthesizing beta-ketone thiosulfone compounds in one step by carrying out bifunctional reaction on arylformyl methylene dimethyl sulfur bromide and thiosulfonic acid ester under the action of sodium carbonate.
Background
The sulfone compound is a common organic intermediate, and plays an extremely important role in the fields of medicines, pesticides, novel functional materials and the like. In medicine, for example, eletriptan, an antimigraine drug, adroquinone, for the treatment of breast cancer, etacoxib, for the treatment of osteoarthritis (ye.s, yang.m, wu.j, chem.commu.2020, 56, 4145-4155), and gamma-secretase inhibitors, for the prevention of alzheimer's disease (i.churcher, d.beer, j.d.best, j.l.castro, e.e.clarke, a.gentry, t.harrison, l.hitzel, e.kay, s.kerrad, h.d.wires, p.m.gutierrez, r.m.smith, p.j.oakley, m.reilly, d.e.shaw, m.s.shearman, m.r.ball, s.williams and j.d.j.wriglg, bioorg.med.chem.lett.,2006,16, 280.) contain sulfone units. In the field of organic pesticides, sulfone compounds have very good antibacterial activity, such as the herbicides carfentrazone (g.mitchell, d.w.bartlett, t.e.m.fraser, t.r.hawkes, d.c.holt, j.k.townson, r.a.wicher, pest manag.sci.2001,57, 120-128.), isoxaflutole (s.taylor-Lovell, g.k.sims, l.m.wax, j.agr.food chem.2002,50, 5626-563.), the insecticides oxycarboxin (k.huster, p.n.moza, a.kettrup, chemosphere.1999,38, 23-3429.). In terms of novel functional materials, the polydiaryl sulfone molecules have special photophysical properties and have wide applications in light emitting diode materials (g.barbarella, l.favaretto, a.zanelli, g.gigli, g.m.mazzeo, m.ani, a.bongini, adv.funct.mater.2005,15, 664-670.). Sulfones are also frequently used as important intermediates for Organic Synthesis (N.S. Simpkins, sulfoxines in Organic Synthesis; pergamon Press: oxford, 1993.). Based on the importance, the development of a new synthesis method of the sulfone compound has great value.
The synthesis of beta-ketosulfolane mainly comprises the following methods: (1) The stevens rearrangement of aryldiazoacetates and thioylides is catalyzed by copper/bipyridine complexes (H.Yuan, T.Nuligoda, H.Gao, C.H.Tung, Z.xu, org.chem.Front.2018,5, 1371-1374.). (2) Copper catalyses the oxidative trifunctional reaction of olefins (s.huang, n.thirupathi, c.h.tung, z.xu, j.org.chem.2018,83, 9449-9455.). (3) A series free radical reaction of thiosulfonate and oxysulfide ylide (f.wang, b.x.liu, w.rao, s.y.wang, org.lett.2020,22, 6600-6604.). The various methods for synthesizing the beta-ketosulfolane have the defects of metal catalysis, difficult preparation of raw materials, complex operation and the like, so the development of a novel method for synthesizing the sulfone compound with high efficiency and convenience has great significance.
We report a bifunctional reaction of arylformyl methylene dimethyl sulfur bromide and thiosulfonic acid ester, and develop a new synthetic method of beta-ketone thiosulfone compounds.
To the best of our knowledge, no literature reports are found which are the same as the present application.

Detailed Description
Example one
To a 25mL glass test tube equipped with a stirring bar was added phenacylidenedimethylthiobromide (0.6 mmol), S-phenylthiobenzenesulfonate (0.5 mmol, sodium carbonate (4 equiv.), 5mL acetonitrile, and finally the tube was sealed with a rubber stopper.A preheated 80 ℃ oil bath was stirred under nitrogen for 4h, after which the reaction mixture was cooled to room temperature, quenched by the addition of saturated sodium chloride solution (10 mL), extracted 3 times with ethyl acetate (15 mL), and the combined organic layers were extracted with anhydrous MgSO 4 Dried and then adsorbed on a rotary evaporator with basic alumina. The residue was purified by flash column chromatography on silica gel (petroleum ether: ethyl acetate = 10: 1-5 as eluent) to give 1-phenyl-2- (benzenesulfonyl) -2- (phenylthio) ethan-1-one as a white solid in 82% yield after purification.
