| titleOfInvention | The synthetic method of 2-imines-1,3-oxygen thia cyclopentenes compounds |
| abstract | The invention provides a kind of 2-imines-1, the synthetic method of 3-oxygen thia cyclopentenes compounds, by 2-iodophenol compounds, isosulfocyanate compound, alkali, mantoquita, N, N, N ' N '-Tetramethyl Ethylene Diamine and water mixing, in stirring at room temperature, reaction 1-8 hour, is extracted with ethyl acetate after reaction terminates, and merges organic layer, use anhydrous sodium sulfate drying again, concentrating under reduced pressure, obtains crude product, crude by column chromatography separating-purifying, obtain required 2-benzo imines-1,3-oxathiin and cyclopentenes compounds.Compared with prior art, the present invention uses water as solvent, environmental friendliness; At room temperature can react, energy-conserving and environment-protective; Utilize " one kettle way " directly to obtain target product in the short period of time, the generation of no coupling product, and without the need to protection of inert gas, operate simpler; Reaction is efficient, productive rate up to 95%, its suitability for industrialized production more favourable. |
