Ko te Roopu Whakamate
Ko te L-Glutamic Acid 5-tert-Butyl Ester (H-Glu(OtBu)-OH) (CAS: 2419-56-9) he waikawa waikawa glutamic, ka taea te whiwhi i te hohenga o te waikawa glutamic me te tert-butyl acetate.
Ko nga waikawa amino me nga pärönaki, e whakamahia ana i roto i te whakahiato peptide, nga takawaenga whakahiato waro, nga takawaenga rongoa, nga reagents biochemical, nga reagents matū.
Taapirihia te 2324g tert-butyl acetate me te 73.5g o te waikawa glutamic ki roto i te 3000mL toru-waha pounamu, whakaohokia, maturuturu 160.8mL o te waikawa perchloric, tauhohe ki te 10 ℃ mo te 48 haora, whakamatao ki te 0 ℃, tāpirihia te 1000mL o te wai, tangohia. tangohia (ko te toenga tert-butyl acetate ka tangohia hei whakarewa), whakakorehia ki te Na2CO3 ki te pH = 8 ~ 9, wehea te wai, ka horoi ki te 400 mL1% Na2CO3 wairewa wai e toru nga wa, ka aro ki te paparanga acetate tert-butyl i raro i te whakaheke. te pehanga ki te whiwhi 42g hinu Glu(OtBu)2 me te hua o te 32.4%.Tāpirihia te 42g o Glu(OtBu)2 ki roto i te 1000mL ipu toru-waha, katahi ka tapirihia te 400mL o te wai me te 11g o CuCl2, whakanekehia te pāmahana ki te 50℃, tauhohenga mo te 12 haora, me te whakarite Cu[Glu(OtBu)]x(x = 1~2);Ka whakahekehia ki te pāmahana rūma, tāpirihia te 19g o tetramethylethylenediamine me te 100mL o te dioxane, ka whakatikahia te pH ki te 8 ~ 9 me te triethylamine, L-Glutamic Acid 5-tert-Butyl Ester i whakaritea.
