Hoʻokipa mau i kā mākou mau hoaaloha a me nā mea kūʻai aku e hele mai e kipa i kā mākou hui a alakaʻi i kā mākou ʻoihana, inā makemake ʻoe i kā mākou mea kūʻai, hiki iā ʻoe ke hoʻouna i kāu ʻike kūʻai ma ka pūnaewele, a e hoʻopili koke mākou iā ʻoe, mālama mākou i kā mākou hui pū ʻana. a makemake i nā mea a pau ma kou ʻaoʻao e maikaʻi.

ʻO 2,5-Dimethoxybenzaldehyde kahi pauka 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 i hoʻemi ʻia i ka 2,5-dimethoxybenzoic acid, benzonitrile a i ʻole benzyl alcohol, 2,5-dimethoxybenzaldehyde ponoʻī nō hoʻi ka waiwai noi kūikawā. 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 loaʻa ka phenamidine i ka hopena maikaʻi ma PD, me ka haʻahaʻa haʻahaʻa a me ka palekana maikaʻi, a ʻo ka synthesis o phenamidine e pono ai ka hoʻohana ʻana i ka 2,5-dimethoxybenzaldehyde i mea hoʻomaka.

Wahi a ke ʻano hana synthesis i hōʻike ʻia ma ka palapala, loaʻa ka 2,5-dimethoxybenzaldehyde 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.
