BOC-N-Methyl-L-alanine (CAS# 16948-16-6) Information
| application | BOC-N-methyl-L-alanine inogona kushandiswa kwete chete yeprotein synthesis, asiwo sechinhu chinonakisa, chekuchengetedza uye chekuchengetedza mumunda wekudya, semishonga yezvigadzirwa zvemishonga mumunda wemishonga uye yakapfava surfactant synthesis mundima yemazuva ese yemakemikari. |
| kugadzirira | tetrahydrofuran (80 mL) mhinduro ye1-boc-alanine (5g, 26.4 mmol) yakawedzerwa, poda yakanaka KOH (10.4g, 187 mmol) yakawedzerwa pa 0 ℃, uye ipapo tetrabutylammonium bisulfate (0.5g, 10% nehuremu) yakawedzerwa. Zvadaro, dimethyl sulfate (10 mL, 105 mmol) yakawedzerwa kudonha kweanopfuura maminetsi gumi nemashanu. Wedzera mamwe maminitsi makumi matatu uye wobva wawedzera mvura (50 mL). Mushure mokukurudzira pakupisa kwekamuri kwemaawa mashanu, 20% ammonium hydroxide aqueous solution (20 mL) yakawedzerwa. Deretsa maitiro ne ether (100 mL), patsanura dhizaini yemvura, uye bvisa iyo organic layer ine saturated NaHCO3 aqueous solution (2 × 40 mL). Iyo yakasanganiswa mvura layer yakaiswa acidified ne1M KHSO4 kusvika pH 1 uye yakabviswa ne ethyl acetate (2 × 200 mL). Iyo organic layers inosanganiswa, yakaomeswa (Na2SO4), yakasefa uye yakanamirwa. Chigadzirwa chinoguma chakaonekwa seBOC-N-methyl-L-alanine. Butter, goho 4.3g, 80%. |
