Isicelo:

N,N,N',N'-Tetramethylchloroformamidinium Hexafluorophosphate (TCFH) (CAS: 94790-35-9), i-coupling reagent ye-peptide synthesis kanye nezinto zokuqala zokulungiselela amanye ama-reagents ahlanganisayo.I-TCFH iyi-reagent enhle yokuhlanganisa i-peptide synthesis synthesis.Njengesisebenzi esivamile sokwenza kusebenze samakhemikhali esigaba esiqinile, i-TCFH ikhuthaza ngokuyinhloko ukwakheka kokuphuma kokuphuma kwe-amine ye-carboxylic acid kune-amide enqubweni yokuhlanganisa ama-amino acid.Iwusizo kakhulu ekuhlanganisweni kwama-amino acid avinjwe kakhulu, futhi inezici zenqubo elula nelula yokuhlanganisa nempilo ende yeshalofu.
I-TCFH iyi-reagent ephephile, ethengekayo ye-ester kanye ne-amide synthesis enzima.
I-TCFH njenge-reagent inezinzuzo ezimbalwa ngaphandle kokuthi iyonga:
- Ngenxa yamandla aphezulu okuhlangana, ingasetshenziswa ekuphenduleni okwenziwe ngaphambilini kuphela ngokusebenzisa ama-couplings e-carbodiimide-mediated, enwebeka ngale ndlela ukusetshenziswa kwayo kokwakhiwa kwama-esters, ama-diacyl amide kanye ne-acylation yama-amine angasebenzi.
- Iqinile, inhlanganisela ezinzile, lapho igcinwe cishe ku-0°C
- Ngokusebenzisa izithasiselo zokuhlanganisa ezitholakala kabanzi usokhemisi angathola isilinganiso esilungile se-reagent ukuze alinganisele phakathi kwesivuno somkhiqizo kanye nokusabela okuseceleni okuhlanganisa ukucwiliswa kwe-epimerization.

Ukulungiselela:

Esikhathini esiyimizuzu emi-2, ku-1,1,3,3-Tetramethylurea (2.5 mL, 21 mmol)/10 mL isixazululo se-toluene ingxenye encane ye-oxalyl chloride (2.0 mL, 23 mmol) yengezwe ngenkathi ingxube yokusabela inyakaziswa. at lokushisa okugeza ice-amanzi.Ngemva kokunyakazisa ekamelweni lokushisa amahora angu-18, ingxube yokusabela yagxiliswa ngaphansi kwengcindezi encishisiwe ibe umthamo ongaba ngu-5 mL futhi imvula ewumphumela yaqoqwa ngokuhlunga.Okuqinile okuqoqiwe kwancibilika cishe ku-20 mL wamanzi kwase kuxutshwa nge-potassium hexafluorophosphate (3.8g, 21 mmol)/50 mL yesisombululo esinamanzi kuyilapho ingxube inyakaziswa ngamandla ekamelweni lokushisa, ukuze kutholwe imvula emhlophe.Imvula iqoqwe ngokuhlunga futhi yomiswa ngaphansi kwe-vacuum.Okuqinile kwabe sekuphathwa cishe ngo-8 mL we-acetone futhi kuhlungwa ukuze kukhishwe izinto ezingancibiliki.I-filtrate ewumphumela yengezwa ngezingxenye ezincane ku-60 mL we-diethyl ether ngokunyakaziswa okunamandla ekamelweni lokushisa.Umkhiqizo ofisa uqoqwe ngokuhlunga futhi womiswa ngaphansi kwe-vacuum ukunikeza u-4.5g (76%).
