Fmoc-L-Aspartic Acid β-tert-Butyl Ester (Fmoc-Asp(OtBu)-OH) (CAS: 71989-14-5) minangka perantara kimia, umume digunakake ing proses sintesis polipeptida, kanggo proteksi asam amino.Asam Fmoc-amino, digunakake ing sintesis peptida, digunakake minangka perantara sintesis organik, perantara farmasi, reagen biokimia utawa reagen kimia.
Preparation: Tambah 581g saka tert-Butyl Acetate lan 133g saka Aspartic Acid kanggo ML botol telung tutuk, nglakoake, lan nambah saka asam perchloric dropwise, reaksi ing 10 ℃ kanggo 48 jam, digawe adhem kanggo 0 ℃, banjur ditambahake 700ml banyu, diekstrak (sisa tert-Butyl Acetate minangka ekstraksi pelarut), dinetralake karo Na2CO3 dadi pH = 7, pamisahan cairan, lapisan tert-Butyl Acetate dikonsentrasi ing tekanan sing dikurangi kanggo entuk campuran Asp(OtBu)2, Asp(OtBu) lan lenga Asp-OtBu, sing digabungake karo lapisan banyu sing bakal digunakake.Campuran asil ditransfer menyang 125 ml telung botol, G cuso4 · 5H2O ditambahake, lan pH disetel dadi 3 kanthi asam hidroklorat pekat.Campuran kasebut diaduk lan digawe panas nganti 50 ℃.Kanggo 12 jam nyiyapake Cu[Asp(OtBu)]x.(x = 1~2);Banjur mudhun menyang suhu kamar, nambah 116.2G tetramethylethylenediamine lan 300ml dioxane, lan banjur nyetel pH kanggo 8 ~ 9 karo triethylamine kanggo nyiyapake Asp(OtBu);banjur nambah 82gFmoc-OSu menyang Asp(OtBu), njaga pH 8~9, reaksi kanggo 8 jam, banjur extract karo etil asetat, acidify, wisuh banyu, distilasi vakum, crystallization, pangatusan, 85g saka Fmoc-L-aspartic acid beta. -tert-butil ester dipikolehi kanthi ngasilake 20,7%.Miturut analisis HPLC saka Fmoc-L-Aspartic Asam β-tert-Butyl Ester.
