Taw qhia

N-Boc-L-aspartic acid yog L-methionine derivative uas muaj cov pab pawg N-tiv thaiv.

 

Zoo:

N-Boc-L-methionine yog cov khoom dawb uas yog soluble hauv qee cov kuab tshuaj organic xws li methanol, ethanol, thiab methylene chloride. Nws yog ruaj khov nyob rau hauv acidic tej yam kev mob tab sis hydrolyzed nyob rau hauv alkaline tej yam kev mob.

 

Siv:

N-Boc-L-methionine yog ib feem siv cov amino acid tiv thaiv pab pawg uas tiv thaiv lwm pab pawg reactive hauv synthesis ntawm cov organic tebchaw.

 

Txoj kev:

Kev npaj ntawm N-Boc-L-methionine feem ntau ua tiav los ntawm cov tshuaj tiv thaiv ntawm N-Boc tiv thaiv pawg ntawm L-methionine. Ib txoj hauv kev yog siv Boc2O (N-butyldicarboxamide) thiab lub hauv paus catalyst muab N-Boc-L-methionine tom qab cov tshuaj tiv thaiv.

 

Cov ntaub ntawv kev nyab xeeb:

N-Boc-L-methionine feem ntau kuj muaj kev nyab xeeb raws li kev sim ua haujlwm ua haujlwm. Nws tuaj yeem ua rau lub qhov muag, tawv nqaij, thiab ua pa ua pa thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag thaum siv nws. Ua tib zoo ua raws li cov kev sim kev nyab xeeb kev ua haujlwm tshwj xeeb thiab yuav tsum tau nruab nrog cov kev tiv thaiv zoo sib xws.
