Isicelo:

I-N-Cbz-L-Valine (Z-Val-OH) (CAS: 1149-26-4) iwuhlobo oluvikelwe yi-N-Cbz lwe-L-Valine.I-N-Cbz-L-Valine iyi-valine evikelwe yi-Cbz futhi isetshenziswa kakhulu emkhakheni wokuhlanganiswa kwezidakamizwa.I-L-Valine iyi-amino acid ebalulekile esetshenziswa njengesithako ekwenziweni kwezimonyo, emikhiqizweni yezemithi, kanye nemikhiqizo yokudla kwezilwane.I-L-Valine ibalulekile futhi ekukhuleni nasekukhishweni kwe-ammonia kubantu.
I-Z-Amino Acid, ingasetshenziswa ku-peptide synthesis, ingasetshenziswa futhi njenge-organic synthesis intermediate, i-pharmaceutical intermediate, i-biochemical reagent noma i-reagent yamakhemikhali.
I-N-Cbz-L-Valine ingasetshenziswa ekwenzeni ama-API afana ne-Imatinib, i-Valaciclovir.
Ukulungiselela thatha u-1.17Kg (10mol) we-L-Valine, u-5L we-2mol/L isisombululo se-sodium hydroxide kanye no-1.06Kg (10mol) we-sodium carbonate kugedlela lokusabela elingu-20L, qala ukunyakazisa, ngemva kokuba i-L-Valine ichithekile ngokuphelele, yehlisa izinga lokushisa ikhambi elingaphansi kuka-0℃, kanye nokuconsa oku-1 okuqukethe u-2.05Kg(12mol) we-benzyl chloroformate, isixazululo se-4-dioxane 5L, izinga lokushisa lesisombululo kwinqubo yokuwisa ligcinwa lingaphansi kuka-20℃, ngemva kokwehla, ukusabela kuba ngu-8h ekamelweni. izinga lokushisa.Ekupheleni kokusabela, uketshezi lokusabela lukhishwa nge-dichloromethane 2.5L, isigaba se-organic siyalahlwa, isigaba se-aqueous sipholile sibe ngaphansi kwe-10 ℃, i-hydrochloric acid egxilile yehla kuze kube yi-pH = 2, bese inyakaziswa ku-10 ℃ i-30min. , inani elikhulu lokuqinile elimhlophe liyancishiswa, ukuhlungwa kuyenziwa, insalela yesihlungi igezwa ngamanzi, okuqinile okumhlophe kufakwa kuhhavini omisiwe we-vacuum ukuze kome, futhi isivuno singama-93.7%.
