Ko ā mātou utu he whakaiti i ngā utu hoko, he tīma moni whiwhi hihiri, he QC motuhake, he wheketere pakari, he ratonga kounga teitei mōLtd., Te Kamupene Hangarau o Wuhan Jingkang, E whakaaro ana tā mātou kamupene ki ngā "utu whaitake, te wā whakaputa pai me te ratonga whai muri i te hoko" hei kaupapa matua mā mātou. Ko tā mātou tumanako ka mahi tahi mātou me ētahi atu kiritaki mō te whanaketanga tahi me ngā painga. E mihi ana mātou ki ngā kaihoko pea ki te whakapā mai ki a mātou.

2,5-DimethoxybenzaldehydeHe paura tioata kōwhai mārama te paura, ko tōna taumaha ngota he 166.18, ā, ko tōna pāmahana kohua he 146°C. Ka wairewa i roto i ngā whakarewa waro pērā i te etanoru me te etera. Ko te nuinga o te wā ka whakamahia hei takawaenga rongoā.

Haunga te whakahāngaitanga, te whakaiti rānei ki te waikawa 2,5-dimethoxybenzoic, te benzonitrile, te benzyl alcohol rānei,2,5-dimethoxybenzaldehydeHe uara tono ahurei anō hoki tōna. Mā te tauhohenga ki ngā matū he momo rōpū mahi rerekē, ka taea te whiwhi i ngā ngota rongoā he rerekē ngā hanganga me ngā pānga rerekē. He mate neurodegenerative noa te mate a Parkinson (PD), ā, ko ōna tohu haumanu matua ko te wiri o te uaua, te pakari, te uaua ki te nekehanga, te tū o te tinana me ngā mate taurite nekehanga. Ka arahi anō hoki te whanaketanga ki te mōhio, te tirohanga, ngā mate mahara me te mate wareware mārama. I tēnei wā, ko te maimoatanga o te PD ko te nuinga o te rongoā rongoā, te rongoā pokanga me te rongoā ira. I roto i te rongoā rongoā, i kitea he pānga pai te phenamidine ki te PD, he iti te paitini me te haumaru pai, ā, ko te hanga o te phenamidine me whakamahi i te2,5-dimethoxybenzaldehydehei rauemi tīmatanga.

E ai ki te tikanga whakahiato i kōrerotia i roto i ngā tuhinga,2,5-dimethoxybenzaldehydeKo te nuinga o te wā ka whiwhi mā te tauhohenga i te 1,4-dimethoxybenzene me te kaihoko formylation. Ko ngā kaihoko formylation ko (1) te ranunga o te 1,1-dichloromethyl ether me te titanium tetrachloride; (2) te ranunga o te N,N-dimethylformamide me te phosphorus oxychloride, he ranunga o te N,N-dimethylformamide me te oxalyl chloride; (3) te ranunga o te N,N-dimethylformamide me te thionyl chloride, he ranunga rānei o te urotropine me te magnesium chloride. Heoi, me whakamahi i te nui o te titanium tetrachloride, te phosphorus oxychloride, te thionyl chloride rānei i ēnei tikanga. He koretake ēnei matū, ā, he ngāwari te pirau, ā, he nui te hau waikawa hydrochloric ka tukuna i te wā o te tauhohenga, kāore e pai ki te taiao, ā, he nui ngā whakaritenga mō te tukanga mahi.

Kua whakaarohia he tikanga hanga hou. Ka whakamahia e tēnei tikanga te 1,4-dimethoxybenzene me te formaldehyde hei rauemi mata, ā, ka mahi i tētahi tauhohenga hononga photooxidative i te aroaro o te hāora me te whakakorikori i raro i te hihi mārama kikorangi hei hanga pai i te 2,5-dimethoxybenzaldehyde. Ka whakamahia e tēnei tikanga te hāora, te hau rānei hei whakakorikori, kāore e whakaputa hau waikawa, ā, he hoa taiao. Hei tāpiri, ka whakamahia e tēnei tikanga te cobalt iti te utu hei whakakorikori, he iti te utu, ā, he pai mō te tono ahumahi.
