Hoʻoikaika mākou i ka holomua a hoʻokomo i nā hopena hou i ka mākeke i kēlā me kēia makahiki no2 5-Dimethoxybenzaldehyde a me 93-02-7, I mea e hoʻokō ai i kā mākou pahuhopu o ka "mea kūʻai mua a me ka pōmaikaʻi like" i ka hui ʻana, hoʻokumu mākou i kahi hui ʻenekinia akamai a me kahi hui kūʻai aku e hoʻolako i ka lawelawe maikaʻi loa e hoʻokō i nā koi o kā mākou mea kūʻai. Welina mai iā ʻoe e hui pū me mākou a hui pū me mākou. ʻO mākou kāu koho maikaʻi loa.
2,5-Dimethoxybenzaldehydehe pauda crystalline melemele māmā me ke kaumaha molekala o 166.18 a me kahi 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 pharmaceutical intermediate.

Ma waho aʻe o ka oxidized a hoʻemi ʻia i ka 2,5-dimethoxybenzoic acid, benzonitrile a i ʻole benzyl alcohol,2,5-dimethoxybenzaldehydeloaʻa iā ia iho ka waiwai noi kūʻokoʻa. Ma ka hana 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 o Parkinson (PD) he maʻi neurodegenerative maʻamau, a ʻo kāna mau hōʻailona koʻikoʻi e pili ana i ka haʻalulu ʻiʻo, ʻoʻoleʻa, paʻakikī o ka neʻe ʻana, ke kū ʻana o ke kino a me nā pilikia kaulike. ʻO ka hoʻomohala hou aʻe e alakaʻi i ka ʻike, ka ʻike, nā pilikia hoʻomanaʻo a me ka dementia maopopo. I kēia manawa, ʻo ka mālama ʻana i ka PD ka mea nui e pili ana i ka lāʻau lapaʻau, ka lāʻau lapaʻau a me ka lāʻau gene. I ka lāʻau lapaʻau, ua ʻike ʻia ka hopena maikaʻi o ka phenamidine i ka PD, me ka haʻahaʻa haʻahaʻa a me ka palekana maikaʻi, a ʻo ka synthesis o ka phenamidine e pono ai ka hoʻohana2,5-dimethoxybenzaldehydei mea hoʻomaka.
E like me ke ʻano synthesis i hōʻike ʻia ma ka palapala,2,5-dimethoxybenzaldehydeloaʻa nui ʻia ma ka hana ʻana i ka 1,4-dimethoxybenzene me kahi mea hana formylation. ʻO nā mea hana formylation ka (1) kahi hui o 1,1-dichloromethyl ether a me titanium tetrachloride; (2) kahi hui o N,N-dimethylformamide a me phosphorus oxychloride, kahi hui o N,N-dimethylformamide a me oxalyl chloride; (3) kahi hui o N,N-dimethylformamide a me thionyl chloride a i ʻole ka hui ʻana o ka urotropine a me ka magnesium chloride. Eia nō naʻe, pono kēia mau ʻano i ka hoʻohana ʻana i ka nui o ka titanium tetrachloride, phosphorus oxychloride a i ʻole thionyl chloride. ʻAʻole paʻa a maʻalahi kēia mau reagents, a ua hoʻokuʻu ʻia ka nui o ke kinoea hydrochloric acid i ka wā o ka hopena, ʻaʻole ia e pili i ke kaiapuni a loaʻa nā koi kiʻekiʻe no ke kaʻina hana.
Ua manaʻo ʻia kahi ala synthesis hou. Hoʻohana kēia ʻano hana i ka 1,4-dimethoxybenzene a me ka formaldehyde e like me nā mea maka, a hana i kahi hopena hoʻohui photooxidative i ke alo o ka oxygen a me ka catalyst ma lalo o ka irradiation kukui polū e hoʻohui pono i ka 2,5-dimethoxybenzaldehyde. Hoʻohana kēia ʻano i ka oxygen a i ʻole ka ea ma ke ʻano he oxidant, ʻaʻole e hoʻopuka i ke kinoea ʻakika, a pili i ke kaiapuni. Eia kekahi, hoʻohana kēia ʻano i ka cobalt cheap ma ke ʻano he catalyst, he haʻahaʻa i ke kumukūʻai a kūpono no ka noi ʻoihana.
