I-Hazard Class IRRITANT
I-L-Glutamic Acid 5-tert-Butyl Ester (H-Glu(OtBu)-OH) (CAS: 2419-56-9) i-glutamic acid derivative, ingatholakala ngokusabela kwe-glutamic acid ne-tert-butyl acetate.
Ama-amino acid kanye nokuphuma kokunye, asetshenziswa ku-peptide synthesis, organic synthesis intermediates, intermediate pharmaceutical, reagents biochemical, chemical reagents.
Ukulungiselela engeza u-2324g we-tert-butyl acetate kanye no-73.5g we-glutamic acid ebhodleleni elinemilomo emithathu engu-3000mL, gudluza, wehlise u-160.8mL we-perchloric acid, uphendule ku-10 ℃ amahora angu-48, upholile ku-0 ℃, engeza u-1000mL wamanzi, khipha amanzi. thatha (i-tert-butyl acetate esele ikhishwa njengesinyibilikisi), yenza kancane nge-Na2CO3 kuya ku-pH = 8~9, uhlukanise uketshezi, bese ugeza ngesisombululo samanzi esingu-400% Na2CO3 izikhathi ezintathu, bese ugxilisa ungqimba lwe-tert-butyl acetate ngaphansi kokuncipha. ingcindezi yokuthola 42g kawoyela Glu(OtBu)2 ngesivuno 32.4%.Engeza u-42g we-Glu(OtBu)2 ebhodleleni elinemilomo emithathu engu-1000mL, bese ufaka u-400mL wamanzi no-11g we-CuCl2, ukhuphule izinga lokushisa libe ku-50℃, usabele amahora angu-12, bese ulungisa i-Cu[Glu(OtBu)]x(x = 1~2);Uma yehliselwa ezingeni lokushisa legumbi, engeza u-19g we-tetramethylethylenediamine no-100mL we-dioxane, bese ulungisa i-pH ibe ngu-8~9 nge-triethylamine, i-L-Glutamic Acid 5-tert-Butyl Ester yalungiswa.
