I-Hazard Class IRRITANT
I-Fmoc-L-Aspartic Acid β-tert-Butyl Ester (i-Fmoc-Asp (OtBu) -OH) (i-CAS: 71989-14-5) yikhemikhali ephakathi, esetyenziswa ngokuqhelekileyo kwinkqubo ye-polypeptide synthesis, ukukhusela i-amino acid.I-Fmoc-amino acids, esetyenziswa kwi-peptide synthesis, esetyenziswa njenge-organic synthesis ephakathi, i-pharmaceutical intermediate, i-biochemical reagent okanye i-chemical reagent.
Ukulungiselela: Yongeza i-581g ye-tert-Butyl Acetate kunye ne-133g ye-Aspartic Acid kwi-ML yebhotile yomlomo emithathu, ugxobhoze, kwaye udibanise i-perchloric acid dropwise, ukuphendula kwi-10 ℃ kwiiyure ezingama-48, ipholile ukuya kwi-0℃, emva koko wongeze i-700ml yamanzi, ikhutshwe (i-tert-Butyl Acetate eseleyo njenge-solvent extraction), ingathathi hlangothi nge-Na2CO3 ukuya kwi-pH = 7, ukwahlula ulwelo, i-tert-Butyl Acetate layer yayigxininiswe phantsi koxinzelelo oluncitshisiweyo lokufumana umxube we-Asp (OtBu) 2, Asp (OtBu) kunye ne-oyile ye-Asp-OtBu, eyayidityaniswe ne-aqueous layer ukuze isetyenziswe.Umxube obangelwayo udluliselwe kwi-125 ml iibhotile ezintathu, i-G cuso4 · i-5H2O yongezwa, kwaye i-pH yahlengahlengiswa kwi-3 kunye ne-concentrated hydrochloric acid.Umxube waxutywa kwaye wafudunyezwa kwi-50℃.Iiyure ezili-12 ukulungiselela iCu[Asp(OtBu)]x.(x = 1~2);Emva koko phantsi kwiqondo lokushisa, yongeza i-116.2G tetramethylethylenediamine kunye ne-300ml dioxane, uze ulungise i-pH kwi-8 ~ 9 kunye ne-triethylamine ukulungiselela i-Asp (OtBu);uze udibanise i-82gFmoc-OSu kwi-Asp (OtBu), ugcine i-pH 8 ~ 9, uphendule kwiiyure ze-8, uze ukhuphe nge-ethyl acetate, i-acidify, uhlambe ngamanzi, i-vacuum distillation, i-crystallization, i-85g ye-Fmoc-L-aspartic acid beta -tert-butyl ester yafunyanwa kwisivuno se-20.7%.Ngohlalutyo lwe-HPLC ye-Fmoc-L-Aspartic Acid β-tert-Butyl Ester.
