Peb lub hom phiaj yuav tsum yog los tsim cov khoom siv tswv yim thiab cov kev daws teeb meem rau cov neeg siv khoom siv kev ua haujlwm zoo heev rau , Txog tam sim no, peb cov khoom cuam tshuam nrog lub tshuab luam ntawv dtg a4 tuaj yeem pom nyob rau ntau lub teb chaws txawv teb chaws nrog rau cov chaw hauv nroog, uas tau nrhiav tom qab yooj yim los ntawm cov phiaj xwm tsheb. Peb txhua tus xav tias tam sim no peb muaj peev xwm ua tiav rau koj nrog cov khoom txaus siab. Xav sau cov lus thov ntawm koj cov khoom thiab tsim kom muaj kev sib koom tes ua haujlwm ntev. Peb cog lus tiag tiag: Csame zoo tshaj plaws, tus nqi zoo dua; pes tsawg tus nqi muag, zoo dua.

2,5-Dimethoxybenzaldehydeyog lub teeb daj crystalline hmoov nrog ib qho hnyav molecular ntawm 166.18 thiab qhov kub ntawm 146 ° C. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether. Nws yog tsuas yog siv los ua tshuaj nruab nrab.

Ntxiv rau qhov raug oxidized los yog txo rau 2,5-dimethoxybenzoic acid, benzonitrile los yog benzyl cawv, 2,5-dimethoxybenzaldehyde nws tus kheej kuj muaj qhov tshwj xeeb daim ntawv thov nqi. Los ntawm kev cuam tshuam nrog cov tshuaj nrog ntau hom kev ua haujlwm, cov tshuaj molecules nrog cov qauv sib txawv thiab cov teebmeem sib txawv tuaj yeem tau txais. Parkinson's disease (PD) yog ib hom kab mob neurodegenerative, thiab nws cov tsos mob tseem ceeb muaj xws li cov leeg nqaij tremor, rigidity, txav tsis yooj yim, lub cev lub cev thiab lub cev tsis sib haum xeeb. Kev loj hlob ntxiv tseem yuav ua rau kev paub, kev nkag siab, kev nco tsis meej thiab pom tseeb dementia. Tam sim no, kev kho mob ntawm PD feem ntau suav nrog kev kho tshuaj, kev kho mob phais thiab kev kho noob. Hauv kev kho tshuaj, phenamidine tau pom tias muaj cov txiaj ntsig zoo ntawm PD, nrog cov tshuaj toxicity tsawg thiab kev nyab xeeb zoo, thiab cov synthesis ntawm phenamidine yuav tsum tau siv 2,5-dimethoxybenzaldehyde ua cov khoom pib.

Raws li cov txheej txheem synthesis qhia hauv cov ntaub ntawv,2,5-dimethoxybenzaldehyde muajFeem ntau yog tau los ntawm reacting 1,4-dimethoxybenzene nrog tus neeg sawv cev formylation. Formylation cov neeg ua haujlwm suav nrog (1) sib xyaw ntawm 1,1-dichloromethyl ether thiab titanium tetrachloride; (2) sib tov ntawm N, N-dimethylformamide thiab phosphorus oxychloride, sib tov ntawm N, N-dimethylformamide thiab oxalyl chloride; (3) sib tov ntawm N, N-dimethylformamide thiab thionyl chloride los yog sib tov ntawm urotropine thiab magnesium chloride. Txawm li cas los xij, cov txheej txheem no yuav tsum tau siv ntau ntawm titanium tetrachloride, phosphorus oxychloride lossis thionyl chloride. Cov reagents no tsis ruaj khov thiab yooj yim decomposed, thiab ib tug loj npaum li cas ntawm hydrochloric acid gas raug tso tawm thaum lub sij hawm cov tshuaj tiv thaiv, uas tsis yog ib puag ncig tus phooj ywg thiab muaj cov kev xav tau siab rau cov txheej txheem ua haujlwm.

Cov txheej txheem tshiab synthesis tau raug npaj. Txoj kev no siv 1,4-dimethoxybenzene thiab formaldehyde ua raw cov ntaub ntawv, thiab ua ib tug photooxidative coupling cov tshuaj tiv thaiv nyob rau hauv lub xub ntiag ntawm oxygen thiab ib tug catalyst nyob rau hauv xiav lub teeb irradiation kom zoo synthesize 2,5-dimethoxybenzaldehyde. Txoj kev no siv cov pa oxygen lossis cua ua cov oxidant, tsis tsim cov pa roj acidic, thiab yog ib puag ncig zoo. Tsis tas li ntawd, txoj kev no siv cov cobalt pheej yig los ua ib qho catalyst, uas yog tus nqi qis thiab tsim nyog rau kev lag luam.
