BOC-N-Methyl-L-alanine （CAS # 16948-16-6) Amakuru
| Porogaramu | BOC-N-methyl-L-alanine ntishobora gukoreshwa gusa muri sintezamubiri ya poroteyine gusa, ariko kandi nk'iyongera uburyohe, uburyo bwo kubungabunga no kubungabunga ibidukikije mu biribwa, nk'ibikoresho fatizo bya farumasi mu buvuzi hamwe na synthesis yoroheje ya surfactant mu murima wa buri munsi. |
| kwitegura | tetrahydrofuran (80 mL) igisubizo cya 1- boc-alanine (5g, 26.4 mmol) yongeyeho, ifu nziza KOH (10.4g, 187) mmol) yongewe kuri 0 ℃, hanyuma tetrabutylammonium bisulfate (0.5g, 10% kuburemere) yongewemo. Hanyuma, dimethyl sulfate (10 mL, 105 mmol) yongewemo ibitonyanga muminota irenga 15. Kangura indi minota 30 hanyuma wongeremo amazi (50 mL). Nyuma yo gukurura ubushyuhe bwicyumba cyamasaha 5, hiyongereyeho 20% hydroxide hydroxide ya amonium (20 mL). Koresha reaction hamwe na ether (100 mL), gutandukanya urwego rwamazi, hanyuma ukuramo urwego kama hamwe numuti wuzuye wa NaHCO3 wuzuye (2 × 40 mL). Amazi avanze yavanze acide hamwe na 1M KHSO4 kugeza pH 1 hanyuma ikuramo hamwe na Ethyl acetate (2 × 200 mL). Ibice kama byahujwe, byumye (Na2SO4), byungururwa kandi byegeranye. Ibicuruzwa byavuyemo byamenyekanye nka BOC-N-methyl-L-alanine. Amavuta, umusaruro 4.3g, 80%. |
Andika ubutumwa bwawe hano hanyuma utwohereze
