2,5-DimethoxybenzaldehydeHe pauka kristal melemele māmā me ke kaumaha molekala o 166.18 a me kahi kiko paila o 146°C. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka ether. Hoʻohana nui ʻia ia ma ke ʻano he mea lapaʻau waena.

Ma waho aʻe o ka hoʻopau ʻia ʻana a hoʻemi ʻia paha i ka 2,5-dimethoxybenzoic acid, benzonitrile a i ʻole benzyl alcohol,2,5-dimethoxybenzaldehydeLoaʻa iā ia iho ka waiwai hoʻohana kūikawā. Ma ka pane ʻana me nā mea me nā ʻano hui hana like ʻole, hiki ke loaʻa nā molekala lāʻau me nā ʻano like ʻole a me nā hopena like ʻole. ʻO ka maʻi Parkinson (PD) kahi maʻi neurodegenerative maʻamau, a ʻo kāna mau hōʻailona lapaʻau nui e pili ana i ka haʻalulu o nā ʻiʻo, ka paʻakikī, nā pilikia neʻe, ke kūlana kino a me nā maʻi kaulike neʻe. E alakaʻi pū ka hoʻomohala hou ʻana i ka ʻike, ka ʻike, nā maʻi hoʻomanaʻo a me ka dementia maopopo. I kēia manawa, ʻo ka mālama ʻana i ka PD e pili ana i ka lāʻau lapaʻau, ka mālama ʻoki kino a me ka lāʻau gene. I ka lāʻau lapaʻau, ua ʻike ʻia he hopena maikaʻi ka phenamidine ma ka PD, me ka haʻahaʻa haʻahaʻa a me ka palekana maikaʻi, a ʻo ka synthesis o phenamidine e pono ai ka hoʻohana ʻana o2,5-dimethoxybenzaldehydema ke ʻano he mea hoʻomaka.

Wahi a ke ʻano hana synthesis i hōʻike ʻia ma ka palapala,2,5-dimethoxybenzaldehydeLoaʻa nui ʻia ma ka hoʻopili ʻana i ka 1,4-dimethoxybenzene me kahi mea hana formylation. ʻO nā mea hana formylation e komo pū me (1) kahi hui ʻana o 1,1-dichloromethyl ether a me titanium tetrachloride; (2) kahi hui ʻana o N,N-dimethylformamide a me phosphorus oxychloride, kahi hui ʻana o N,N-dimethylformamide a me oxalyl chloride; (3) kahi hui ʻana o N,N-dimethylformamide a me thionyl chloride a i ʻole kahi hui ʻana o urotropine a me magnesium chloride. Eia nō naʻe, pono kēia mau ʻano hana i ka hoʻohana ʻana i ka nui o ka titanium tetrachloride, phosphorus oxychloride a i ʻole thionyl chloride. He paʻa ʻole kēia mau reagents a maʻalahi hoʻi e palaho, a ua hoʻokuʻu ʻia ka nui o ke kinoea hydrochloric acid i ka wā o ka hana ʻana, ʻaʻole ia he mea pili i ke kaiapuni a he mau koi kiʻekiʻe no ke kaʻina hana.

Ua hāpai ʻia kekahi ʻano hana hoʻohui hou. Hoʻohana kēia ʻano hana i ka 1,4-dimethoxybenzene a me ka formaldehyde ma ke ʻano he mea maka, a hana i kahi hopena hoʻopili photooxidative i ke alo o ka oxygen a me kahi mea hoʻoulu ma lalo o ka hoʻomālamalama ʻana o ka mālamalama polū e hana pono i ka 2,5-dimethoxybenzaldehyde. Hoʻohana kēia ʻano hana i ka oxygen a i ʻole ka ea ma ke ʻano he oxidant, ʻaʻole ia e hana i ke kinoea waikawa, a he aloha i ke kaiapuni. Eia kekahi, hoʻohana kēia ʻano hana i ka cobalt haʻahaʻa ma ke ʻano he mea hoʻoulu, he haʻahaʻa ke kumukūʻai a kūpono no ka hoʻohana ʻoihana.
