2,5-Dimethoxybenzaldehyde CAS 93-02-7
Ko te 2,5-Dimethoxybenzaldehyde he paura tioata kowhai marama me te taumaha ngota o te 166.18 me te ira koropuke o te 146°C. He wairewa i roto i nga whakarewa pararopi penei i te waihano me te etera. Ka whakamahia te nuinga hei takawaenga rongoa.

I tua atu i te oxidized, i whakahekehia ranei ki te waikawa 2,5-dimethoxybenzoic, benzonitrile, benzyl alcohol ranei, ko te 2,5-dimethoxybenzaldehyde ano he uara tono ahurei. Ma te tauhohenga ki nga matū me nga momo roopu mahi rereke, ka taea te whiwhi i nga ngota ngota tarukino he rereke nga hanganga me nga paanga rereke. Ko te mate o Parkinson (PD) he mate neurodegenerative noa, a ko ona tohu haumanu matua ko te wiri uaua, te uaua, te uaua o te neke, te tuunga o te tinana me nga raruraru taurite neke. Ko etahi atu whakawhanaketanga ka arahi ano ki te mohiotanga, te tirohanga, te mate mahara me te mate mate. I tenei wa, ko te nuinga o te maimoatanga o te PD ko te rongoa rongoa, te rongoa rongoa me te rongoa ira. I roto i te rongoa rongoa, i kitea he pai te painga o te phenamidine ki te PD, he iti te paitini me te pai o te haumaru, me te whakahiato o te phenamidine me whakamahi te 2,5-dimethoxybenzaldehyde hei rauemi timatanga.
E ai ki te tikanga whakahiato i korerotia i roto i nga tuhinga, ko te 2,5-dimethoxybenzaldehyde te nuinga o te whiwhi ma te tauhohe i te 1,4-dimethoxybenzene me te kaihoko formylation. Kei roto i nga mea whakangao (1) he ranunga o te 1,1-dichloromethyl ether me te titanium tetrachloride; (2) he ranunga o te N,N-dimethylformamide me te phosphorus oxychloride, he ranunga o te N,N-dimethylformamide me te oxalyl chloride; (3) he ranunga o te N,N-dimethylformamide me te thionyl chloride he ranunga ranei o te urotropine me te konupora chloride. Engari, ko enei tikanga me whakamahi te nui o te titanium tetrachloride, phosphorus oxychloride, thionyl chloride ranei. Ko enei reagents kaore i te pumau, ka ngawari te pakaru, ka tukuna he nui o te hau waikawa waikawa waikawa i te wa o te tauhohenga, kaore i te pai ki te taiao me te nui o nga whakaritenga mo te tukanga mahi.
He tikanga whakahiato hou kua tohua. Ka whakamahia e tenei tikanga te 1,4-dimethoxybenzene me te formaldehyde hei rauemi mata, ka mahi i te tauhohenga honohono photooxidative i te aroaro o te hāora me te whakakōkī i raro i te irradiation marama kikorangi kia pai te synthesize 2,5-dimethoxybenzaldehyde. Ko tenei tikanga ka whakamahi i te hāora, i te hau ranei hei waikura, kaore e whakaputa i te hau waikawa, he pai ki te taiao. I tua atu, ko tenei tikanga e whakamahi ana i te cobalt iti hei whakakorikori, he iti te utu me te pai mo te tono ahumahi.
