Maikaʻi Maikaʻi 2 a 3 La Puka i ka Puka Hoʻouna wikiwiki i ka pauda melemele CAS 93-02-7 2, 5-Dimethoxybenzaldehyde

E noʻonoʻo i ke kuleana piha e hoʻokō i nā koi āpau o kā mākou mea kūʻai; loaʻa i nā holomua mau ma ke kūʻai ʻana i ka holomua o kā mākou mea kūʻai aku; E ulu a lilo i hoa hui hope loa o nā mea kūʻai aku a hoʻonui i ka makemake o nā mea kūʻai aku no ka maikaʻi maikaʻi 2 a 3 mau lā Puka i ka puka Hoʻouna wikiwiki i ka pauka melemele.CAS 93-02-7 2, 5-Dimethoxybenzaldehyde, Loaʻa mākou i ka pilina hohonu me nā haneli o nā hale hana kokoke i Kina. Hiki ke hoʻohālikelike ʻia nā mea a mākou e hōʻike nei me nā kelepona like ʻole. E koho iā mākou, ʻaʻole mākou e mihi iā ʻoe!
E noʻonoʻo i ke kuleana piha e hoʻokō i nā koi āpau o kā mākou mea kūʻai; loaʻa i nā holomua mau ma ke kūʻai ʻana i ka holomua o kā mākou mea kūʻai aku; ulu e lilo i hoa hui mau hope loa o nā mea kūʻai aku a hoʻonui i ka makemake o nā mea kūʻai aku noCAS 93-02-7 a me Dsip, Mālama kā mākou hui i ka manaʻo hoʻokele o "mālama i ka hana hou, e ʻimi i ka maikaʻi". Ma ke kumu o ka hōʻoia ʻana i nā pono o nā huahana i loaʻa, hoʻomau mākou i ka hoʻoikaika a hoʻonui i ka hoʻomohala huahana. Ke koi nei kā mākou hui i ka hana hou e hāpai i ka hoʻomohala hoʻomau o ka ʻoihana, a lilo mākou i mea hoʻolako kiʻekiʻe kiʻekiʻe.

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 i2,5-dimethoxybenzoic acid, benzonitrile a i ʻole benzyl waiʻona, 2,5-dimethoxybenzaldehyde ponoʻī nō hoʻi ka waiwai hoʻohana 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.
