BOC-N-Methyl-L-alanine (CAS# 16948-16-6) Ulwazi
| isicelo | I-BOC-N-methyl-L-alanine ayinakusetyenziswa kuphela kwi-protein synthesis, kodwa kwakhona njenge-flavour enhancer, i-preservative kunye ne-preservative kwintsimi yokutya, njengezixhobo ezikrwada zamayeza kwintsimi yeyeza kunye ne-mild surfactant synthesis kwintsimi yemichiza yemihla ngemihla. |
| ukulungiselela | I-tetrahydrofuran (80 mL) isisombululo se-1-boc-alanine (5g, 26.4 mmol) yongezwa, i-powder powder KOH (10.4g, 187) mmol) yongezwa kwi-0 ℃, kwaye ke i-tetrabutylammonium bisulfate (0.5g, i-10% ngesisindo) yongezwa. Emva koko, i-dimethyl sulfate (10 mL, 105 mmol) yongezwa kwi-dropwise ngaphezulu kwemizuzu eyi-15. Gxuma enye imizuzu engama-30 kwaye wongeze amanzi (50 mL). Emva kokuvuselela kwiqondo lokushisa kweeyure ze-5, i-20% ye-ammonium hydroxide isisombululo se-aqueous (20 mL) yongezwa. Nciphisa ukusabela nge-ether (100 mL), yahlula umaleko wamanzi, kwaye ukhuphe i-organic layer nge-saturated NaHCO3 isisombululo samanzi (2 × 40 mL). Umaleko wamanzi oxutyiweyo ufakwe iasidi nge-1M I-KHSO4 ukuya kwi-pH 1 kwaye ikhutshwe nge-ethyl acetate (2 × 200 ml). Iingqimba zezinto eziphilayo zidibeneyo, zomisiwe (Na2SO4), zihluzwe kwaye zigxininiswe. Imveliso efunyenweyo ichongiwe njenge-BOC-N-methyl-L-alanine. Ibhotolo, isivuno 4.3g, 80%. |
