Isicelo:

N, N, N', N'-Tetramethylchloroformamidinium Hexafluorophosphate (TCFH) (CAS: 94790-35-9), ukudibanisa i-reagent ye-peptide synthesis kunye nokuqala izinto zokulungiselela ezinye ii-reagents zokudibanisa.I-TCFH yinto efanelekileyo yokudibanisa i-peptide synthesis ye-non-hygroscopic.Njengesixhobo sokusebenza ngokubanzi sekhemistri yesigaba esiluqilima, i-TCFH ikhuthaza ikakhulu ukusekwa kwe-carboxylic acid amine derivatives kune-amide kwinkqubo yokudibanisa amino acid.Iluncedo kakhulu ekudityanisweni kwe-amino acids ethintelwe kakhulu, kwaye ineempawu zenkqubo elula nelula yokudibanisa kunye nobomi obude beshelufu.
I-TCFH yindawo ekhuselekileyo, efikelelekayo ye-reagent ye-ester kunye ne-amide synthesis enzima.
I-TCFH njenge-reagent ineenzuzo ezininzi ngaphandle koqoqosho:
-Ngenxa yokudibanisa amandla aphezulu, inokuthi isetyenziswe kwiimpendulo ezenziwe ngaphambili kuphela ngokusebenzisa i-carbodiimide-mediated couplings, ukwandisa ngale ndlela isicelo sayo sokwenziwa kwe-esters, i-diacyl amides kunye ne-acylation ye-amines engasebenziyo.
– Liqinile, lizinze ngokufanelekileyo, xa ligcinwe malunga ne-0°C
– Ukusebenzisa izongezelelo zokudibanisa ezikhoyo ngokubanzi ikhemisti inokufumana umlinganiselo ofanelekileyo wereagent ukulinganisa phakathi kwemveliso yemveliso kunye neempendulo zecala kubandakanya i-epimerization.

Ukulungiselela:

Ngethuba lemizuzu emi-2, ukuya kwi-1,1,3,3-Tetramethylurea (2.5 mL, 21 mmol) / 10 mL isisombululo se-toluene inxalenye encinci ye-oxalyl chloride (2.0 mL, 23 mmol) yongezwa ngelixa umxube wokuphendula uvuselelwe. kwiqondo lobushushu lokuhlambela lamanzi omkhenkce.Emva kokuvuselela kwiqondo lokushisa kweeyure ze-18, umxube wokuphendula wawugxininiswe phantsi koxinzelelo oluncitshisiweyo ukuya kumthamo omalunga ne-5 mL kunye ne-precipitate efunyenweyo iqokelelwe ngokuhluzwa.Isiqina esiqokelelweyo sanyibilikiswa malunga ne-20 mL yamanzi kwaye emva koko sanyangwa nge-potassium hexafluorophosphate (3.8g, 21 mmol)/50 mL yesisombululo esinamanzi ngelixa umxube ushukunyiswa ngamandla kwiqondo lobushushu begumbi, ukufumana imvula emhlophe.Imvula yaqokelelwa ngokuhluzwa kwaye yomiswa phantsi kwevacuum.Isiqina saye sanyangwa malunga ne-8 mL ye-acetone kwaye yahluzwa ukususa izinto ezinganyibilikiyo.I-filtrate ebangelwayo yongezwa kwiingxenye ezincinci kwi-60 mL ye-diethyl ether kunye nokuvuselela ngamandla kwiqondo lokushisa.Imveliso efunwayo yaqokelelwa ngokuhluzwa kwaye yomiswa phantsi kwevacuum ukunika i-4.5g (76%).
