BOC-N-Methyl-L-alanine (CAS# 16948-16-6) Macluumaad
| codsi | BOC-N-methyl-L-alanine loo isticmaali karaa ma aha oo kaliya loogu talagalay synthesis protein, laakiin sidoo kale sida xoojinta dhadhanka, ilaalinta iyo ilaalinta duurka cuntada, sida alaabta ceeriin farmashiyaha ee beerta daawada iyo synthesis khafiif ah surfactant duurka kiimikada maalin kasta. |
| diyaarinta | tetrahydrofuran (80 mL) xal 1-boc-alanine (5g, 26.4 mmol) ayaa lagu daray, budada ganaaxa KOH (10.4g, 187) mmol) ayaa lagu daray 0 ℃, ka dibna tetrabutylammonium bisulfate (0.5g, 10% miisaan ahaan) ayaa lagu daray. Ka dib, dimethyl sulfate (10 ml, 105 mmol) waxaa lagu daray hoos wax ka badan 15 daqiiqo. Walaaq 30 daqiiqo oo kale oo ku dar biyo (50 ml). Ka dib marka lagu walaaqo heerkulka qolka 5 saacadood, 20% ammonium hydroxide xal aqueous (20 ml) ayaa lagu daray. Ku qas falcelinta ether (100 mL), kala saar lakabka biyaha, oo soo saar lakabka organic leh NaHCO3 xal aqueous ah oo buuxa (2 × 40 mL). Lakabka biyaha isku dhafka ah waxaa lagu daray 1M KHSO4 ilaa pH 1 waxaana lagu soo saaray ethyl acetate (2 × 200 mL). Lakabyada organic waa la isku daray, la qalajiyey (Na2SO4), la sifeeyay oo xoogga saaray. Badeecada ka soo baxday waxaa loo aqoonsaday BOC-N-methyl-L-alanine. Subagga, waxa soo saara 4.3g, 80%. |
