Cov Ntawv Thov
(S) -} 2 {- methyl-cbs-oxazaborolidine feem ntau yog siv ua achairal catalyst nyob rau hauv asymmetric txo, tshwj xeeb rau kev txo qis ntawm ketones los tsim cov cawv nyias nyias nyias. Cov dej cawv no ua cov khoom tseem ceeb hauv kev sib xyaw ntawm cov tshuaj, cov khoom siv ntuj, thiab zoo nkauj rau cov nyiaj txiag yog qhov tseem ceeb rau kev ua haujlwm biological. Cov compound kuj tseem ua haujlwm hauvKev Kawm Txuj Ci thiab Kev Tshawb FawbRau kev tsim cov txheej txheem asymmetric tshiab, suav nrog cov catalytic hydrogenations, hloov hydrogen ntau, thiab lwm yam kev hloov pauv hloov tshiab. Nws cov enantioselectivity ua rau nws haum rau synthesizing cov tsev uas muaj ntau lawm hauv kev tsim cov tshuaj chiral, agnchemicals, thiab cov ntaub ntawv tshwj xeeb. Txuas ntxiv, nws yog siv nyob rau hauvKev Kawm Siv LausThiab kev ua haujlwm ntawm kev ua yeeb yam ntawm cov kev phiv, muab cov kev pom zoo rau hauv cov kev tiv thaiv txoj hauv kev thiab txhim kho kev ua haujlwm ntawm cov khoom siv hluavtaws.
Cov txiaj ntsig
Cov txiaj ntsig ntawm (s)- 2 {- methyl-cbs-oxazaborolidine qia los ntawm nwsHigh enantioselectivity, efficiency, thiab ua hauj lwm yooj yimCov. Nws tso cai rau Chemists los tsim cov chiral cawv nrog kev ua kom zoo nkauj, txo qhov xav tau ntawm cov kauj ruam daws teeb meem thiab cov khib nyiab. Lub catalyst yog qhov txiaj ntsig ntawm cov khoom siv qis, uas txhim kho tus nqi- efficabicy thiab kev ntev hauv cov ntawv thov loj. NwsKev ruaj khov nyob rau hauv cov qauv kev tshwm simSaib xyuas kev ua tau zoo ib yam, thaum nws compatibility nrog ntau cov kuab tshuaj thiab substrates muab versatility hauv ntau yam transformations. Tsis tas li ntawd, nws siv cov kev txhim kho kev txhim kho ntawm ib puag ncig cov lus asymmetric los ntawm kev txo qis ntawm stoichiometric chairal reagents. Zuag qhia tag nrho, nws yooj yim cov synthesis ntawm siab- tus nqi chiral tebchaw, kev txhim kho tshuaj kho kom nrawm dua thiab tshuaj lom neeg raug tshuaj zoo.
Tag
Hauv cov ntsiab lus, (cov) - 2 {{{{}} methyl-cbs-oxexaborolidine qhov tseem ceeb chiral txo cov khoom siv asymmetricive thiab enantioselective synthesis. Nws sib xyaw ntawm kev xaiv siab, ruaj khov, thiab kev siv hluav taws xob ua rau nws yog qhov cuab yeej tseem ceeb hauv cov tshuaj, tshuaj lom neeg thiab kev kawm. Los ntawm kev ua kom muaj cov khoom siv dawb zoo ntawm cov khoom siv dawb huv thiab chairal tsev thaiv, nws txuas ntxiv mus rau kev txhim kho kev ua tiav.
