Application:

N,N,N',N'-Tetramethylchloroformamidinium Hexafluorophosphate (TCFH) (CAS: 94790-35-9), coupling reagent ye peptide synthesis uye kutanga zvinhu zvekugadzirira mamwe macoupling reagents.TCFH yakanaka isiri-hygroscopic peptide synthesis coupling reagent.Seyakajairwa activation reagent yeakasimba phase chemistry, TCFH inonyanya kusimudzira kuumbwa kwecarboxylic acid amine derivatives pane kuti amide mukubatanidza maitiro emaamino acid.Inobatsira zvikuru pakubatana kweamino acids akavharirwa zvakanyanya, uye ine hunhu hweiyo yakapusa uye yakanakira synthesis maitiro uye hurefu hwehupenyu hwesherufu.
TCFH yakachengeteka, inokwanisika reagent ye ester uye yakaoma amide synthesis.
TCFH se reagent ine zvakati wandei zvakanakira kunze kwekuve nehupfumi:
-Nekuda kwehukuru hwekubatanidza potency, inogona kushandiswa mukuita kwakamboitwa chete uchishandisa carbodiimide-mediated couplings, ichiwedzera nenzira iyi mashandisirwo ayo ekuumbwa kweesters, diacyl amides uye acylation yeasina-reactive amines.
- Yakasimba, yakagadzikana zvine mutsindo, kana yakachengetwa kutenderedza 0°C
-Kushandisa iyo yakawanda inowanikwa coupling additives chemist inogona kuwana yakakwana reagent ratio yekuenzanisa pakati pegoho rechigadzirwa uye maitiro epadivi anosanganisira epimerization.

Kugadzirira:

Kwenguva yemaminetsi maviri, kusvika ku1,1,3,3-Tetramethylurea (2.5 mL, 21 mmol)/10 mL toluene mhinduro chikamu chidiki cheoxalyl chloride (2.0 mL, 23 mmol) chakawedzerwa apo musanganiswa wekuita wakamutswa. pachando-mvura yekugeza tembiricha.Mushure mekusimudzira pamhepo tembiricha kwemaawa gumi nemasere, musanganiswa wekuita wakaiswa pasi pekumanikidzwa kwakaderedzwa kusvika kuvhoriyamu ye5 mL uye iyo inokonzeresa precipitate yakaunganidzwa nekusefa.Iyo yakaoma yakaunganidzwa yakanyungudutswa muinenge 20 mL yemvura ichibva yabatwa ne potassium hexafluorophosphate (3.8g, 21 mmol)/50 mL yeaqueous solution uku musanganiswa wacho uchimutswa zvine simba pakudziya kwekamuri, kuti uwane mvura yakachena.Iyo mvura yakaunganidzwa nekusefa uye yakaomeswa pasi pevacuum.Iyo yakasimba yakazobatwa neinenge 8 mL yeacetone uye yakasefa kubvisa isinganyungudika.Iyo filtrate yakaguma yakawedzerwa muzvikamu zviduku kusvika ku60 mL ye diethyl ether ine simba rinokurudzira pakupisa kwekamuri.Chigadzirwa chaidiwa chakaunganidzwa nekusefa uye chakaomeswa pasi pevacuum kupa 4.5g (76%).
