| titleOfInvention | A kind of method that green catalysis synthesizes 1,8 dioxo decahydro acridine derivatives |
| abstract | The invention discloses a kind of method that green catalysis synthesizes 1,8 dioxo decahydro acridine derivatives, belong to technical field of organic synthesis.The mol ratio of aromatic amine, 5 in the synthetic reaction, the cyclohexanedione of 5 dimethyl 1,3 and aromatic aldehyde is 1：2：1, the mole of trisulfonic acid radical ion liquid catalyst is the 0.8~1% of aromatic aldehyde used, the volume that reaction dissolvent ethanol is counted using milliliter as aromatic aldehyde by mM in terms of 3~5 times of mole, reaction pressure is an atmospheric pressure, reflux time is 3~4h, and reaction is cooled to room temperature after terminating, and has a large amount of solids to separate out, suction filtration, target product is obtained after the vacuum drying of gained filter residue.The present invention is compared with using the synthetic method of other ionic-liquid catalysts, with catalyst activity is high, biodegradable is good, raw material availability is high, reaction condition is gentle and the features such as whole preparation process simple to operate, is easy to industrialize large-scale application. |
