57224-63-2 - Isicelo:

I-ZL-Threonine Methyl Ester (Z-Thr-OMe) (i-CAS: 57224-63-2) ingasetyenziselwa njenge-intermediates kwi-organic synthesis kunye ne-pharmaceutical intermediates, esetyenziswa kwi-peptide synthesis.

57224-63-2 - Ukulungiselela:

Yongeza i-70g L-threonine kunye ne-ML methanol kwi-1.1000ml i-flask enentamo ezintathu, lawula ubushushu obungaphantsi kwe-0℃, i-64 ml ye-thionyl chloride yongezwa nge-dropwise.Emva kokugqitywa kwesongezo, umxube wawushushu ukuze uhlaziye i-reflux iiyure ze-4.Idistillation phantsi koxinzelelo oluncitshisiweyo ukuya komile kwi-55℃.Unike i-100g ye-L-threonine methyl ester hydrochloride njengeoli.Ukusabela okulandelayo kubalwe ngesivuno se-100%;2. Kwi-beaker ye-2L, yongeza i-100g ye-L-threonine methyl ester hydrochloride, i-600ml yamanzi, kwaye ulungelelanise i-pH ye-sodium bicarbonate kwi-alkaline, i-z-cl G yongezwa nge-dropwise kwaye i-pH yahlengahlengiswa kwi-8-9 kunye ne-2MOC / l sodium hydroxide yokusabela.Ekupheleni kwempendulo, yongeza i-ethyl acetate 1L ukuyikhupha, yithathe, ihlambe ngamanzi angama-500ml, ihlambe nge-500ml ye-saturated brine, yomise nge-100g anhydrous sodium sulfate, ihluze ngokufunxa, idistilled phantsi koxinzelelo olucuthiweyo de ibe yinto eqinile. i-precipitates, yongeza i-petroleum ether 600Ml crystallization, i-Suction filtration, ukomisa ukufumana i-N-benzyloxycarbonyl-l-threonine methyl ester 140g, isivuno se-89.1%.
