Ntle le ho ba oxidized kapa ho fokotsoa ho 2,5-dimethoxybenzoic acid, benzonitrile kapa benzyl joala, 2,5-dimethoxybenzaldehyde ka boeona le eona e na le boleng bo ikhethang ba ts'ebeliso. Ka ho sebetsana le lintho tse nang le mefuta e fapaneng ea lihlopha tse sebetsang, limolek'hule tsa lithethefatsi tse nang le mekhoa e fapaneng le liphello tse fapaneng li ka fumanoa. Boloetse ba Parkinson (PD) ke lefu le tloaelehileng la neurodegenerative, 'me matšoao a lona a mantlha a kenyelletsa ho thothomela ha mesifa, ho satalla, mathata a ho sisinyeha, boemo ba 'mele le mathata a ho leka-lekanya ho sisinyeha. Ntlafatso e eketsehileng e tla boela e lebise tlhokomelo, temoho, mathata a ho hopola le 'dementia' e totobetseng. Hajoale, kalafo ea PD e kenyelletsa haholo kalafo ea lithethefatsi, kalafo ea opereishene le kalafo ea lefutso. Ka phekolo ea lithethefatsi, phenamidine e fumanoe e e-na le phello e ntle ho PD, e nang le chefo e tlaase le polokeho e ntle, 'me motsoako oa phenamidine o hloka tšebeliso ea 2,5-dimethoxybenzaldehyde e le ntho e qalang.
Ho ea ka mokhoa oa ho kopanya o tlalehiloeng libukeng, 2,5-dimethoxybenzaldehyde e fumanoa haholo-holo ka ho arabela 1,4-dimethoxybenzene ka moemeli oa formylation. Lisebelisoa tsa formylation li kenyelletsa (1) motsoako oa 1,1-dichloromethyl ether le titanium tetrachloride; (2) motsoako oa N, N-dimethylformamide le phosphorus oxychloride, motsoako oa N, N-dimethylformamide le oxalyl chloride; (3) motsoako oa N, N-dimethylformamide le thionyl chloride kapa motsoako oa urotropine le magnesium chloride. Leha ho le joalo, mekhoa ena e hloka tšebeliso ea tekanyo e ngata ea titanium tetrachloride, phosphorus oxychloride kapa thionyl chloride. Li-reagents tsena ha li tsitse ebile li senyeha habonolo, 'me palo e kholo ea khase ea hydrochloric acid e lokolloa nakong ea karabelo, e seng botsoalle ba tikoloho ebile e na le litlhoko tse phahameng bakeng sa ts'ebetso ea ts'ebetso.
Ho hlahisitsoe mokhoa o mocha oa ho kopanya. Mokhoa ona o sebelisa 1,4-dimethoxybenzene le formaldehyde e le lisebelisoa tse tala, 'me o etsa photooxidative coupling reaction ka pel'a oksijene le catalyst tlas'a mahlaseli a khanyang a maputsoa ho kopanya hantle 2,5-dimethoxybenzaldehyde. Mokhoa ona o sebelisa oksijene kapa moea e le oxidant, ha o hlahise khase e nang le asiti, hape o baballa tikoloho. Ho phaella moo, mokhoa ona o sebelisa cobalt e theko e tlaase e le mokelikeli, o theko e tlaase ebile o loketse ts'ebeliso ea indasteri.
