Hazard Class IRRITANT
L-Glutamic Acid 5-tert-Butyl Ester (H-Glu (OtBu)-OH) (CAS: 2419-56-9) yog glutamic acid derivative, tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm glutamic acid thiab tert-butyl acetate.
Amino acids thiab derivatives, siv nyob rau hauv peptide synthesis, organic synthesis intermediates, tshuaj intermediates, biochemical reagents, tshuaj reagents.
Kev npaj ntxiv 2324g ntawm tert-butyl acetate thiab 73.5g ntawm glutamic acid rau hauv 3000mL peb lub qhov ncauj lub raj mis, do, poob 160.8mL ntawm perchloric acid, teb ntawm 10 ℃ rau 48 teev, txias rau 0 ℃, ntxiv 1000mL dej, extract noj (qhov seem ntawm tert-butyl acetate yog muab rho tawm ua hnyav), nruab nrab nrog Na2CO3 rau pH = 8 ~ 9, cais cov kua, tom qab ntawd ntxuav nrog 400 mL1% Na2CO3 aqueous tov peb zaug, thiab mloog zoo rau tert-butyl acetate txheej hauv qab txo. siab kom tau 42g ntawm cov roj Glu (OtBu) 2 nrog ib tug yield ntawm 32.4%.Ntxiv 42g ntawm Glu (OtBu) 2 rau hauv 1000mL peb lub qhov ncauj lub raj mis, tom qab ntawd ntxiv 400mL dej thiab 11g ntawm CuCl2, nce qhov kub thiab txias rau 50 ℃, ua rau 12 teev, thiab npaj Cu[Glu(OtBu)] x(x) = 1~2);Thaum nws txo qis hauv chav sov, ntxiv 19g ntawm tetramethylethylenediamine thiab 100mL ntawm dioxane, thiab tom qab ntawd kho cov pH rau 8 ~ 9 nrog triethylamine, L-Glutamic Acid 5-tert-Butyl Ester tau npaj.
