    ʻO ka hoʻohana ʻana a me ka hoʻohana ʻana o Di-tert-butyl dicarbonate

    Na Waiwai Kemika ʻO ka Di-tert-butyl dicarbonate (BOC Anhydride, DiBOC) he kala ʻole i ke keʻokeʻo a hiki i nā kristal melemele, paʻa paʻa a i ʻole wai maʻemaʻe.Hehee ia a puni ka lumi wela (mp=23°C).ʻAʻole ia e decompose ma kēia a i ʻole ka wela iki aʻe.No ka laʻana, hoʻomaʻemaʻe maʻamau ia e ka distillation ma lalo o ke kaomi hoʻemi ʻia ma nā mahana a hiki i kahi o 65°C.Ma nā wela kiʻekiʻe e hoʻoheheʻe ʻia i isobutene, t-butyl alcohol a me carbon dioxide.
    Hoʻohana ʻO Di-tert-butyl dicarbonate (Boc2O) he mea hoʻohana nui ia no ka hoʻokomo ʻana i nā hui pale i ka peptide synthesis.He kuleana koʻikoʻi ia i ka hoʻomākaukau ʻana o 6-acetyl-1,2,3,4-tetrahydropyridine ma o ka hana ʻana me 2-piperidone.Hoʻohana ia ma ke ʻano he pūʻulu pale i hoʻohana ʻia i ka solid phase peptide synthesis.
    Hoʻomākaukau ʻO ka hoʻomākaukau ʻana i ka Di-tert-butyl dicarbonate penei: Ua hoʻohui ʻia ka wai paʻakai paʻakai monoester 2g o N, N-dimethylformamide, 1g pyridine, 1g o triethylamine, Hoʻoluʻu i -5 ~ 0 ° C, 60g diphosgene ua mālie. hoʻohui dropwise i loko o 1.5h dropwise hoʻohui ua piha, mehana i ka lumi wela (25 ° C), incubated no 2h, ka pane ua ae e ku ma hope o filtration, holoi organic solution.Hoʻomaloʻo ʻia me ka magnesium sulfate anhydrous, ua hoʻoheheʻe ʻia ka mea hoʻoheheʻe ma ke kaomi ʻana i ka lewa e hāʻawi i ka hua ʻai 65 ~ 70g.Ma hope o ka hoʻoluʻu a me ka crystallization, ua loaʻa ka 57-60g o di-tert-butyl dicarbonate i kahi hua o 60-63%.
    Wehewehe ChEBI: ʻO ka di-tert-butyl dicarbonate he acyclic carboxylic anhydride.He mea pili i ka waika dicarbonic.
    Nā pane ʻO ka hopena o nā aniline i hoʻololi ʻia me Boc2O i ke alo o kahi nui stoichiometric o 4-dimethylaminopyridine (DMAP) i loko o kahi mea hoʻoheheʻe inert (acetonitrile, dichloromethane, ethyl acetate, tetrahydrofuran, toluene) ma ka lumi wela e alakaʻi i ka aryl isocyanates i loko o ka nui o yie. min.
    Ua kipa hou ʻia ʻo Di-tert-butyl dicarbonate a me 4-(dimethylamino)pyridine.ʻO kā lākou hopena me nā amine a me nā waiʻona
    Ka wehewehe nui di-tert-butyl dicarbonate (Boc2O) he reagent i hoʻohana nui ʻia no ka hoʻokomo ʻana i ka hui pale Boc i nā hana amine.Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe wai i kekahi mau hopena kūlohelohe, ʻoi aku me nā waikawa carboxylic, kekahi mau pūʻulu hydroxyl, a i ʻole me nā nitroalkanes mua.
    Pilikia He mea hoʻonāukiuki hiki ke hōʻeha nui i ka maka;Hiki ke hoʻoulu i ka ʻili;ʻona loa ma ka inhalation
    ʻO ke ahi a me ka pahū Hiki ke ahi
    Na Hana Hoomaemae E hoʻoheheʻe i ka ester ma ka hoʻomehana ʻana ma ~35o, a hoʻoheheʻe ʻia i loko o kahi ʻā.Inā hōʻike ʻo IR a me NMR (1810m 1765 cm-1, ma CCl4 1.50 singlet) i ka haumia loa, a laila holoi me ka nui like o ka H2O i loko o ka ʻakika citric e hoʻokaʻawale iki ka papa wai, e hōʻiliʻili i ka papa organik a maloʻo ma luna o MgSO4 anhydrous. a hoʻoheheʻe ʻia i loko o kahi ʻūhā.[Pope et al.Org Synth 57 45 1977, Keller et al.Org Synth 63 160 1985, Grehn et al.Angew Chem 97 519 1985.] PALAPALA.
