Isicelo:

I-Fmoc-L-Aspartic Acid β-tert-Butyl Ester (Fmoc-Asp(OtBu)-OH) (CAS: 71989-14-5) iyikhemikhali ephakathi, evame ukusetshenziswa kwinqubo ye-polypeptide synthesis, ukuze kuvikelwe i-amino acid.Ama-Fmoc-amino acids, asetshenziswa ku-peptide synthesis, asetshenziswa njenge-organic synthesis intermediate, pharmaceutical intermediate, reagent biochemical noma i-chemical reagent.
Ukulungiselela: Faka u-581g we-tert-Butyl Acetate kanye no-133g we-Aspartic Acid ebhodleleni le-ML elinemilomo emithathu, ugovuze, bese wengeza i-perchloric acid dropwise, ukusabela ku-10℃ amahora angu-48, kupholiswe ku-0℃, bese wengeza u-700ml wamanzi, ikhishiwe (i-tert-Butyl Acetate esele njengesithako se-solvent), ingathathi hlangothi nge-Na2CO3 kuya ku-pH = 7, ukuhlukaniswa koketshezi, ungqimba lwe-tert-Butyl Acetate lwagxiliswa ngaphansi kwengcindezi encishisiwe ukuze kutholwe ingxube ye-Asp(OtBu)2, Asp(OtBu) kanye namafutha e-Asp-OtBu, ahlanganiswe nongqimba olunamanzi oluzosetshenziswa.Ingxube ewumphumela idluliselwe ku-125 ml amabhodlela amathathu, i-G cuso4 · 5H2O yanezelwa, futhi i-pH yashintshwa yaba ngu-3 nge-concentrated hydrochloric acid.Ingxube yashukunyiswa futhi yashiswa ku-50℃.Amahora angu-12 ukulungiselela i-Cu[Asp(OtBu)]x.(x = 1~2);Bese wehlela ekamelweni lokushisa, engeza i-116.2G tetramethylethylenediamine kanye ne-300ml dioxane, bese ulungisa i-pH ibe ngu-8~9 nge-triethylamine ukuze ulungiselele i-Asp(OtBu);bese wengeza u-82gFmoc-OSu ku-Asp(OtBu), gcina i-pH 8~9, sabela amahora angu-8, bese ukhipha nge-ethyl acetate, i-acidify, geza ngamanzi, i-vacuum distillation, icrystallization, ukomisa, 85g ye-Fmoc-L-aspartic acid beta -tert-butyl ester itholwe ngesivuno esingu-20.7%.Ngokuhlaziywa kwe-HPLC kwe-Fmoc-L-Aspartic Acid β-tert-Butyl Ester.
