I-L-tert-Leucinol (i-CAS: 112245-13-3), ingasetyenziswa kwi-peptide synthesis, uhlobo lokuphendula: isisombululo se-peptide synthesis.Inokusetyenziswa kwakhona njenge-organic synthesis ephakathi, i-pharmaceutical intermediate, i-biochemical reagent okanye i-reagent yekhemikhali.I-amino acid eluncedo esetyenziswa kwiindlela ezahlukeneyo zokusabela kwe-asymmetric.
I-L-tert-Leucinol inokufumaneka ngokunciphisa amaqela e-carboxyl ukusuka kwi-L-tert-leucine.I-arhente yokunciphisa ingakhethwa Kwi-sodium borohydride kunye ne-lithium tetrahydroaluminum.
Ukulungiselela ukongeza (83.04g,4eq) i-sodium borohydride, i-2L eyomileyo i-tetrahydrofuran, i-L-tert-Leucine 120g kwi-5L ye-flask emithathu yomlomo.Phantsi kokhuseleko lweebhaluni zenitrogen, i-760mL ye-4 ye-hydrofuran isisombululo se-iodine (231g,1eq) ithotywa kancinane kwindawo yokuhlamba umkhenkce nge-0℃ ukuze isabele ngokupheleleyo.Emva kokuwisa nokushukumisa de kungakhutshwa rhasi, emva koko shushu kunye ne-reflux iiyure ezili-18, uphole ukuya kubushushu begumbi, uze wehlise kancinci i-300ml yemethanol ukucacisa umxube.Gxuma i-30min ukususa intlama emhlophe kwi-solvent, kwaye uyinyibilikise kwi-800mL 20% KOH.Kwisisombululo.Isisombululo sobushushu begumbi saxutyushwa nge-4h, kwaye sakhutshwa nge-1.5L dichloromethane amaxesha ama-3 ngexesha ngalinye, isigaba se-organic sadityaniswa, sahlanjwa ngamanzi anetyuwa ahluthisiweyo, somiswa nge-anhydrous sodium sulfate kwaye sigxininiswe yi-spin evaporation ukufumana isivuno esimhlophe se-semi-solid 97g. 90%.
