Peb vam tias yuav koom tes nrog ntau tus neeg siv khoom rau kev sib koom tes thiab cov txiaj ntsig. Peb txais tos cov neeg yuav khoom tuaj yeem tiv tauj peb.
2,5-Dimethoxybenzaldehydeyog ib qho hmoov crystalline daj daj nrog lub molecular hnyav ntawm 166.18 thiab lub boiling point ntawm 146 ° C. Nws yog soluble nyob rau hauv cov organic solvents xws li ethanol thiab ether. Nws yog feem ntau yog siv raws li ib tug kws intermediate.

Ntxiv rau qhov raug oxidized lossis txo qis rau 2,5-dimethoxybenzoic acid, benzonitrile lossis benzyl cawv,2,5-dimethoxybenzaldehydenws tus kheej kuj muaj tus nqi siv tshwj xeeb. 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. Kab mob Parkinson (PD) yog ib qho kab mob neurodegenerative, thiab nws cov tsos mob tseem ceeb suav nrog cov leeg nqaij tshee, rigidity, teeb meem txav mus los, lub cev posture thiab kev txav mus los sib npaug. Kev txhim kho ntxiv kuj tseem yuav ua rau kev lees paub, kev pom, kev nco tsis zoo thiab kev puas tsuaj pom tseeb. Tam sim no, kev kho mob ntawm PD feem ntau suav nrog kev kho mob tshuaj, kev phais mob thiab kev kho mob gene. Hauv kev kho mob tshuaj, phenamidine tau pom tias muaj txiaj ntsig zoo rau PD, nrog rau kev lom tsawg thiab kev nyab xeeb zoo, thiab kev tsim cov phenamidine xav tau kev siv2,5-dimethoxybenzaldehydeua ib qho khoom pib.
Raws li txoj kev sib xyaw ua ke tau tshaj tawm hauv cov ntaub ntawv,2,5-dimethoxybenzaldehydefeem ntau yog tau los ntawm kev sib xyaw 1,4-dimethoxybenzene nrog tus neeg sawv cev formylation. Cov neeg sawv cev formylation suav nrog (1) qhov sib xyaw ntawm 1,1-dichloromethyl ether thiab titanium tetrachloride; (2) qhov sib xyaw ntawm N, N-dimethylformamide thiab phosphorus oxychloride, qhov sib xyaw ntawm N, N-dimethylformamide thiab oxalyl chloride; (3) qhov sib xyaw ntawm N, N-dimethylformamide thiab thionyl chloride lossis qhov sib xyaw ntawm urotropine thiab magnesium chloride. Txawm li cas los xij, cov txheej txheem no xav tau kev siv ntau ntawm titanium tetrachloride, phosphorus oxychloride lossis thionyl chloride. Cov reagents no tsis ruaj khov thiab yooj yim decomposed, thiab ntau ntawm hydrochloric acid roj raug tso tawm thaum lub sijhawm sib xyaw, uas tsis yog tus phooj ywg ib puag ncig thiab muaj cov kev xav tau siab rau cov txheej txheem ua haujlwm.
Muaj ib txoj kev tsim tshiab uas tau muab tso tawm. Txoj kev no siv 1,4-dimethoxybenzene thiab formaldehyde ua cov khoom siv raw, thiab ua cov tshuaj photooxidative coupling reaction nyob rau hauv qhov muaj oxygen thiab catalyst nyob rau hauv lub teeb xiav irradiation kom ua tau zoo synthesize 2,5-dimethoxybenzaldehyde. Txoj kev no siv oxygen lossis cua ua oxidant, tsis tsim cov roj acidic, thiab yog tus phooj ywg ib puag ncig. Tsis tas li ntawd, txoj kev no siv cobalt pheej yig ua catalyst, uas pheej yig thiab haum rau kev siv hauv kev lag luam.
