Siyathemba ukuba uya kuyifumana le nto uyifunayo apha, ukuba akunjalo, nceda uqhagamshelane nathi ngokukhawuleza. Siyazingca ngenkonzo yabathengi ephezulu kunye nempendulo. Enkosi ngeshishini lakho kunye nenkxaso!
2,5-Dimethoxybenzaldehydei-crystalline powder eluhlaza kunye ne-molecular weight 166.18 kunye neqondo lokubilisa le-146 ° C. Iyanyibilika kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-ether. Isetyenziswa ikakhulu njenge pharmaceutical intermediate.

Ukongeza kwi-oxidized okanye ukunciphisa i-2,5-dimethoxybenzoic acid, i-benzonitrile okanye i-benzyl alcohol,2,5-dimethoxybenzaldehydengokwayo inexabiso elilodwa lesicelo. Ngokuphendula ngezinto ezineentlobo ezahlukeneyo zamaqela asebenzayo, iimolekyuli zamachiza ezinezakhiwo ezahlukeneyo kunye nemiphumo eyahlukeneyo inokufumaneka. Isifo sikaParkinson (PD) sisifo esiqhelekileyo se-neurodeergenerative, kwaye iimpawu zaso eziphambili zeklinikhi ziquka ukungcangcazela kwemisipha, ukuqina, ubunzima bokuhamba, ukuma komzimba kunye nokuphazamiseka kokuhamba kakuhle. Uphuhliso olongezelelweyo luya kukhokelela ekuqaphelisweni, ukuqonda, ukuphazamiseka kwememori kunye nesifo sengqondo esixhalabisayo. Okwangoku, unyango lwePD ikakhulu lubandakanya unyango lweziyobisi, unyango lotyando kunye nonyango lwemfuza. Kunyango lweziyobisi, i-phenamidine yafunyanwa inefuthe elihle kwi-PD, enetyhefu ephantsi kunye nokhuseleko oluhle, kwaye ukuhlanganiswa kwe-phenamidine kufuna ukusetyenziswa.2,5-dimethoxybenzaldehydenjengento yokuqala.
Ngokwendlela yokudibanisa echazwe kuncwadi,2,5-dimethoxybenzaldehydeifunyenwe ikakhulu ngokusabela kwi-1,4-dimethoxybenzene kunye ne-agent ye-formylation. I-Formylation agents ziquka (1) umxube we-1,1-dichloromethyl ether kunye ne-titanium tetrachloride; (2) umxube we-N, N-dimethylformamide kunye ne-phosphorus oxychloride, umxube we-N, N-dimethylformamide kunye ne-oxalyl chloride; (3) umxube we-N, N-dimethylformamide kunye ne-thionyl chloride okanye umxube we-urotropine kunye ne-magnesium chloride. Nangona kunjalo, ezi ndlela zifuna ukusetyenziswa kwesixa esikhulu se-titanium tetrachloride, i-phosphorus oxychloride okanye i-thionyl chloride. Ezi reagents aziqinisekanga kwaye zibole ngokulula, kwaye isixa esikhulu segesi ye-hydrochloric acid ikhutshwa ngexesha lokuphendula, elingenabume bendalo kwaye lineemfuno eziphezulu zenkqubo yokusebenza.
Kuye kwacetywa indlela entsha yokudibanisa. Le ndlela isebenzisa i-1,4-dimethoxybenzene kunye ne-formaldehyde njengezinto eziluhlaza, kwaye yenza i-photooxidative coupling reaction xa kukho i-oksijini kunye ne-catalyst phantsi kwe-irradiation yokukhanya okuluhlaza ukuze idibanise ngokufanelekileyo.2,5-dimethoxybenzaldehyde. Le ndlela isebenzisa ioksijini okanye umoya njenge-oxidant, ayivelisi igesi eneasidi, kwaye ihambelana nokusingqongileyo. Ukongeza, le ndlela isebenzisa i-cobalt encinci njenge-catalyst, ephantsi kwexabiso kwaye ifanele ukusetyenziswa kwezoshishino.
