| titleOfInvention | A kind of preparation method of 1,4-oxothia-3,5-dialdehyde cyclohexadiene compound |
| abstract | The invention provides a preparation method of a 1,4-oxothia-3,5-dialdehyde-based cyclohexadiene compound. The invention adds compound 1, compound 2, solvent, catalyst, The oxidant and additives were reacted in a stirred oil bath at 55-65°C for 2.0 h, and the progress of the reaction was monitored by thin-layer chromatography until the reaction was complete; then the saturated sodium thiosulfate solution was added and mixed, and then ethyl acetate was added to extract 2-4 Second, the combined organic phases are collected and washed with saturated brine. The collected organic phases are dried with anhydrous sodium sulfate, the solvent is evaporated under reduced pressure, and the residue is separated and purified by silica gel column chromatography to obtain compound 3; the reaction conditions of the present invention are mild and the synthesis route is short. , safe operation, insensitive to air and other characteristics, has great industrial application value; . |
