Taw qhia
N-BOC-trans-4-hydroxy-L-proline methyl ester, tag nrho lub npe N-tert-butoxycarbonyl-trans-4-hydroxy-L-proline methyl ester, yog cov organic compound.
Zoo:
N-BOC-trans-4-hydroxy-L-proline methyl ester yog dawb crystalline khoom.
Siv:
N-BOC-trans-4-hydroxy-L-proline methyl ester feem ntau yog siv los ua cov amino acid tiv thaiv pawg hauv cov organic synthesis chemistry. Nws tuaj yeem siv los ua cov pab pawg tiv thaiv zoo los tiv thaiv cov pab pawg hydroxyl hauv cov amino acids kom tsis txhob muaj kev cuam tshuam tsis zoo hauv kev sib txuas.
Txoj kev:
Kev npaj ntawm N-BOC-trans-4-hydroxy-L-proline methyl ester feem ntau yog tau los ntawm reacting N-BOC-4-hydroxy-L-proline nrog methanol. N-BOC-4-hydroxy-L-proline yog reacted nrog ib tug activator (xws li DCC los yog DIC) los tsim ib tug activated ester, thiab ces methanol yog ntxiv rau react nrog nws los tsim N-BOC-trans-4-hydroxy- L-proline methyl ester. Lub hom phiaj cov khoom yog tau los ntawm crystallization los yog lwm yam kev sib cais thiab purification txoj kev.
Cov ntaub ntawv kev nyab xeeb: Thaum nws los txog rau cov tshuaj synthesis, kev siv cov cuab yeej thiab cov kev sim yuav tsum muaj kev sib raug zoo. Hauv kev ua haujlwm hauv chaw kuaj mob, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag, thiab ua kom muaj cua zoo. Yog tias koj muaj kev tsis xis nyob hauv lub cev lossis lwm yam kev mob tshwm sim, koj yuav tsum nrhiav kev kho mob tam sim ntawd.
