YieldReaction ConditionsOperation in experiment
79% General procedure: Diselenide was added to a solution of thiol (equivalents are given in table) in 2 mL of anhydrous solvent under a N2 atmosphere. The reaction mixture was stirred for 30 min at a given temperature in table. The haloaryl aldehyde (100 mg) was added to the reaction mixture in a portion and the mixture was stirred at a given temperature for 15 min. A base (equivalents are given in table) was added to the reaction mixture and stirring was continued for an additional 15 min. The progress of the reaction was followed by TLC analysis. When the starting material was disappeared, the mixture was concentrated in vacuo and the residue was extracted with CH2Cl2 (3 .x. 25 mL). The combined organic layer was dried over anhydrous MgSO4 and the solvent was removed in vacuo. The crude product was purified by silica-gel column chromatography, eluting with an ethyl acetate-hexane solution. Yields are given in table.
79% With DL-dithiothreitol; potassium carbonate; In N,N-dimethyl-formamide; at 20℃; General procedure: 10096] In Experimental Example 3, dithiothreitol (DTT) was used as the reducing agent and dimethylformaldehyde (DMF) was used as the solvent to prepare a selenyl-substituted aromatic aldehyde compound. The diselenide compound as represented by general formula A-Se?-Se-A, the aromatic aldehyde starting material, and the base were not limited in kind and various kinds thereof were used for the experiment.10097] To be specific, as the diselenide compound, dimethyldiselenide having a methyl group (Me) as the functional group A, diphenyldiselenide having a phenyl group (Ph) as the functional group A, or dibenzyldiselenide having a benzyl group (13n) as the functional group A was used. As the aromatic aldehyde starting material, various aromatic aldehyde materials having an electron donating substituent or an electron withdrawing substituent were used. Formulas thereof are provided in the following Table 3. Further, as the base, K2C03 as a weak base or DI3U as a strong base was used. In all cases, about 2.5 eq. of the base was used. Differences in percent yield of the product caused by such differences in reaction conditions are shown in the following Table 3.10098] In the following Table 3, K2C03 was used as the base and a reaction temperature was kept at about 800 C. for reaction condition A, K2C03 was used as the base and a reaction temperature was kept at room temperature for reaction condition A?, DI3U was used as the base and a reaction temperature was kept at room temperature for reaction condition B, and DI3U was used as the base and a reaction temperature was kept at about 80° C. for reaction condition C:.
79% With DL-dithiothreitol; potassium carbonate; In N,N-dimethyl-formamide; at 20℃; General procedure: In this Experimental Example 3, celecoxib carbonyl-order to produce a substituted aromatic aldehyde-based compound, as the dithiol reducing agent HauteRay was used Tall (dithiothreitol, DTT), it was used as dimethyl formaldehyde (DMF) as the solvent. The SunDi-selenide compounds represented by bansik Se-Se-A-A, the aromatic aldehyde-based starting material, and the base is one kindsNot fixed to the experiment was changed variously while. Specifically, the di-selenide compound is a functional group AA methyl group (Me) of dimethyl selenide (dimethyldiselenide), the functional group A is diphenyl selenide phenyl group (Ph)(Diphenyldiselenide), it was used dibenzylideneacetone di-selenide (dibenzyldiselenide) or the functional group A is benzyl group (Bn).In addition, the aromatic aldehyde-based starting material is, in various directions with the electron-donating substituent groups or electron-withdrawing substituentsWas used as the aldehyde-group-based material, these more specific formula was shown in the following Table 3. In addition, theExamples of the base was used as the weak base is K2CO3, the strong base or DBU, the base is used per 2.5 equivalent in all cases.Such differencespercent yield of the product that appears due to the difference of reaction conditions are listed in Table 3 to. doingIn Table 3, the reaction conditions, when A is maintained and the reaction temperature using K2CO3 as the base with 80 , reaction conditions, A 'If one is using K2CO3 as the base, and maintaining the reaction temperature to room temperature, the reaction conditions, B is a DBU as the baseAnd is used when maintaining the reaction temperature to room temperature, the reaction conditions, the reaction temperature is 80 C and using DBU as the baseIf it kept in a :
With 1,4-dithio-D,L-threitol; potassium carbonate; In N,N-dimethyl-formamide; at 20℃; In Experimental Example 3, in order to prepare a selenyl-substituted aromatic aldehyde-based compound,As the reducing agent, dithiothreitol (DTT) was used,Dimethylformaldehyde (DMF) was used as the solvent.A diselenide compound represented by the above general formula A-Se-Se-A,The aromatic aldehyde-based starting material,And the base was experimented while varying the base without being fixed. Specifically, as the above-mentioned diselenide compound, dimethyldiselenide whose functional group A is methyl group (Me)Diphenyldiselenide wherein the functional group A is a phenyl group (Ph), Or dibenzyldiselenide in which the functional group A is a benzyl group (Bn). As the aromatic aldehyde-based starting material,Having an electron-donating substituent or an electron-withdrawing substituent Various aromatic aldehyde-based materials were used,These more specific formulas are shown in Table 3 below.As the base, K2CO3 which is weak base or DBU which is strong base was used, The bases were used in 2.5 equivalents in all cases. The difference inpercent yield of the product due to the difference in the reaction conditions is as shown in Table 3 below.In the following Table 3, the reaction condition A is K2CO3 And the reaction temperature was maintained at 80 ° C, The reaction condition A' was carried out using K2CO3 as the baseWhen the reaction temperature is maintained at room temperature,Reaction condition B is the case where DBU is used as the base, the reaction temperature is maintained at room temperature, and reaction condition C is the case where DBU is used as the base and the reaction temperature is maintained at 80°C.
