Pamusoro pekuve oxidized kana kuderedzwa kusvika ku2,5-dimethoxybenzoic acid, benzonitrile kana benzyl doro, 2,5-dimethoxybenzaldehyde pachayo inewo yakasarudzika kukosha kwekushandisa. Nekuita nezvinhu zvine marudzi akasiyana emapoka anoshanda, mamorekuru ezvinodhaka ane zvimiro zvakasiyana uye akasiyana mhedzisiro anogona kuwanikwa. Chirwere cheParkinson (PD) chirwere chakajairika cheurourodegenerative, uye zviratidzo zvayo zvekiriniki zvinosanganisira kudengenyeka kwemhasuru, kusimba, kunetseka kufamba, kumira kwemuviri uye kusagadzikana kwekufamba. Kumwe kusimukira kunozotungamira mukuzivikanwa, kuona, kusagadzikana kwendangariro uye kuparara kuri pachena. Parizvino, kurapwa kwePD kunonyanya kusanganisira kurapwa kwezvinodhaka, kurapwa kwekuvhiya uye gene therapy. Mukurapa kwezvinodhaka, phenamidine yakawanikwa iine simba rakanaka paPD, ine chepfu yakaderera uye kuchengeteka kwakanaka, uye synthesis ye phenamidine inoda kushandiswa kwe2,5-dimethoxybenzaldehyde sechinhu chekutanga.
Zvinoenderana neiyo synthesis nzira yakataurwa mumabhuku, 2,5-dimethoxybenzaldehyde inonyanya kuwanikwa nekuita 1,4-dimethoxybenzene ine formylation agent. Formylation agents anosanganisira (1) musanganiswa we1,1-dichloromethyl ether uye titanium tetrachloride; (2) musanganiswa weN,N-dimethylformamide uye phosphorus oxychloride, musanganiswa weN,N-dimethylformamide uye oxalyl chloride; (3) musanganiswa weN,N-dimethylformamide uye thionyl chloride kana musanganiswa weurotropine uye magnesium chloride. Zvisinei, nzira idzi dzinoda kushandiswa kwetitanium tetrachloride yakawanda, phosphorus oxychloride kana thionyl chloride. Aya ma reagents haana kugadzikana uye akaora nyore nyore, uye yakawanda yehydrochloric acid gasi inoburitswa panguva yekuita, iyo isingabatanidzi kwezvakatipoteredza uye ine zvinodiwa zvakanyanya pakuita basa.
Nzira itsva yekubatanidza yakatsanangurwa. Iyi nzira inoshandisa 1,4-dimethoxybenzene uye formaldehyde seyakagadzirwa, uye inoita photooxidative coupling reaction muhupo hweokisijeni uye catalyst pasi peblue light irradiation kuti inyatso gadzira 2,5-dimethoxybenzaldehyde. Iyi nzira inoshandisa mweya weokisijeni kana mhepo seoxidant, haiburitse gasi rine acidic, uye inochengetedza zvakatipoteredza. Uye zvakare, iyi nzira inoshandisa yakachipa cobalt sechinhu chinokonzeresa, icho chakaderera mumutengo uye chakakodzera kushandiswa kwemaindasitiri.
