95% With cadmium sulphide In methanol at 20℃; for 0.416667 h; Irradiation General procedure: In the experimental procedure for catalytic reaction, amixture of aldehyde (3 mmol), 2-aminothiophenol (3 mmol) and CdSnanosphere (5 mg) was taken in a 100 ml double walled quartz beaker flaskhaving water inlet and outlet to maintain the temperature of the reactionvessel at room temperature in methanol (20 ml). The beaker was exposed tovisible light under stirring condition for the required time period (Table 3).After completion of the reaction (monitored by TLC and GC), methanol wasevaporated by rotary and the product was dissolved in dichloromethane. Thecatalyst was separated from the reaction mixture by centrifugation.Dichloromethane was then evaporated to dryness and the product waspurified by column chromatography using silica gel G60.
91% With lithium bromide In ethanol at 25 - 30℃; for 0.25 h; Sonication General procedure: Aromatic aldehydes (1.0 mmol), o-aminothiophenol (1.0 mmol), and lithiumbromide (20 mol percent) in ethanol (5 mL) were added into a 50-mL round-bottomedflask. The reaction flask was placed in the ultrasonic cleaner bath with the surface ofreactants slightly lower than the water level and irradiated at 25–30 C for theperiod of time indicated in Table 4. The progress of the reaction was monitored byTLC, using petroleum ether/ethyl acetate (8:2) as a solvent system. Aftercompletion of the reaction, the reaction mixture was poured into ice-cold water.The precipitate was filtered off and washed with water, dried, and purified bycrystallization from ethanol as solvent to afford pure product.
89.2% at 25 - 30℃; for 1.4 h; Sonication General procedure: Aromatic aldehydes (2, 1.0 mmol), o-aminothiophenol (1, 1.0 mmol), FeCl3/Montmorillonite K-10 (160 mg, 0.1 mmol, based on FeCl3) and absolute methanol (5 mL) were added into a 25 mL conical flask. The reaction flask was placed in the ultrasonic cleaner bath, where the surface of reactants was slightly lower than the water level and irradiated at 25–30 °C for the period of time (sonication was continued until aromatic aldehydes disappeared as indicated by TLC) as indicated in Tables 1–4 . After completion of the reaction, the reaction mixture was dissolved in ethyl acetate and FeCl3/Montmorillonite K-10 was filtered off. The filtrate was concentrated and purified by silica-gel column chromatography (200–300 mesh) using petroleum ether or the mixture of petroleum ether and ethyl acetate as eluent to give a light yellow crystalline solid. All of the products described herein were previously reported in the literatures [16–35]. The authenticity of the products was established by spectroscopic data and by comparing their melting points with literature values. brown crystals, IR (KBr, cm-1): 3099, 3004, 2934, 1616, 1604, 1584, 1559, 1529, 1478, 1462, 1427, 1387, 1364, 1315, 1279, 1256, 1194, 1124, 1033, 1011, 894, 872, 776, 756, 727; 1H NMR: δH 9.85 (s, 1H, OH), 8.06 (d, J = 8.2 Hz, 1H, ArH), 7.89 (d, J = 7.9 Hz, 1H, ArH), 7.75 (d, J = 1.8 Hz, 1H, ArH), 7.56 (dd, 1H, J1 = 8.2 Hz, J2 = 1.9 Hz, ArH), 7.48-7.51 (m, 1H, ArH), 7.37-7.39 (m, 1H, ArH), 7.03 (d, J = 8.2 Hz, 1H, ArH), 4.00 (s, 3H, CH3); 13C NMR: δC 168.2, 154.0, 148.6, 147.0, 134.8, 126.3, 126.2, 124.9, 122.7, 122.0, 121.5, 114.8, 109.3, 56.2; m/z (ESI): 258 [M+H]+.
85%
Stage #1: With sodium hydrogen sulfate In ethanol
Stage #2: Reflux
General procedure: Equimolar mixture of NaHSO3 (1.25 g, 0.012 mol) and corresponding aldehyde, viz. anisaldehyde (1.63 g, 0.012 mol) for mpb, vanillin (1.82 g, 0.012 mol) for mhpb, and salicylaldehyde (1.47 g, 0.012 mol) for hpbH, were refluxed in ethanol (15 mL) for 15–20 min. To the mixture o-aminothiophenol (1.25 g, 0.01 mol) was added and continued to reflux for 4–5 h. On slow cooling, colorless crystalline compound formed in each case was filtered, washed with water, recrystallized from ethanol, and dried over fused CaCl2. The solids were recrystallised from hot ethanol (scheme 1).
73.4% With sodium metabisulfite In N,N-dimethyl-formamideReflux General procedure: Sodium metabisulfite (0.49 g, 2.5 mmol) was added to a DMF solution of 2-aminothiophenol (2.50 g, 20 mmol) and 4-hydroxybenzaldehyde (2.46 g, 20.2 mmol ). The reaction mixture was stirred and heated to reflux for 2–2.5 h. The progress of reaction was monitored periodically by TLC for completion. Then the mixture was poured into crushed ice, the formed precipitate was separated by filtration and washing to obtain 4-(benzothiazol-2-yl)phenol 4a. Other benzothiazole intermediates 4-(benzothiazol-2-yl)-2-methoxyphenol 4b and 3-(benzothiazol-2-yl)phenol 4c were prepared using a similar synthetic method.21 (see Supplementary file.)
55.6% at 20℃; for 22 h; Inert atmosphere General procedure: To a stirred solution or suspension of substituted benzaldehydes (1.33 mmol, 1a-1l) in MeOH (3-7 mL), 2-aminothiophenol (1.60 mmol) was added and the reaction mixture was stirred at room temperature for 5-96 h. Work-up was conducted by one of the following three methods (Methods A-C). Method A: After evaporation of methanol, the resulting solid was filtered and the filter cake was washed with hexane, methylene chloride, ethyl acetate, and/or cold methanol. Method B: After evaporation of methanol, the resultant residue was dissolved in a small amount of methylene chloride, ethyl acetate, and/or cold methanol, followed by the addition of hexane. After cooling, the resulting precipitate was filtered and washed with hexane, methylene chloride, ethyl acetate, and/or cold methanol. Method C: After evaporation of half the volume of methanol, the reaction mixture was kept in a refrigerator, or water (20 ml) was added to the reaction mixture before refrigerator storage. The resulting precipitate was filtered and the filter cake was washed with hexane, methylene chloride, ethyl acetate, and/or cold methanol. In the cases of compounds, 2b and 2k, flash column chromatography (hexane/methylene chloride = 4/1 to 2/1 for 2b; methylene chloride/MeOH = 90/1 and then methylene chloride only for 2k) was conducted for further purification. The title products (2a-2l) were generated in yields ranging from 15.2percent to 82.6percent.
47.1% With montmorillonite K-10; air In ethanol at 20℃; for 40 h; General procedure: Aldehyde (2, 1.0 mmol) and o-aminothiophenol (1, 1.0 mmol) were mixed inabsolute ethanol (10 mL) in a 50-mL three-necked flask equipped with a watercooledcondenser and a gas inlet, as reported elsewhere [45]. The solution wasstirred at room temperature, then montmorillonite K-10 (25 mg) was added. Air wasbubbled continuously through the reaction system, at a speed of 60 bubbles perminute on average, by means of a small air pump. After completion of the reaction(monitored by TLC) the catalyst was recovered by filtration and washed with EtOH.The filtrate was concentrated and purified by short column chromatography on silicagel, with petroleum ether or a mixture of petroleum ether and ethyl acetate aseluent, to give the pure product. The products (3a–r) are all known compounds andwere identified by 1H NMR spectroscopy, by comparison of their melting pointswith those reported in the literature, and by comparison of their TLC Rf values withthose of standards.
20.23% for 24 h; Reflux General procedure: A mixture of 2-aminothiophenol (0.32 ml, 3 mmol), 0.30 ml(3 mmol) of benzaldehyde and 5 ml of pyridine in a 50 mlround-bottomed flask was refluxed for 24 hrs. Workup includedcooling the reaction mixture and transferred into 50ml of HCl 0.5 N solution. Precipitates formed were filteredand washed with water and dried at 60-70°C to dryness togive brown needle.
