Diethyl azodicarboxylate, conventionally abbreviated li DEAD thiab qee zaum raws li DEADCAT, yog cov organic compound nrog cov qauv qauv CH3CH2O2CN=NCO2CH2CH3. Nws cov qauv molecular muaj lub hauv paus azo ua haujlwm pab pawg, RN=NR, flanked los ntawm ob pawg ethyl ester. Cov kua txiv kab ntxwv-liab no yog ib qho tseem ceeb reagent tab sis kuj txaus ntshai heev thiab tawg thaum cua sov. Yog li ntawd, kev lag luam xa khoom ntawm cov ntshiab diethyl azodicarboxylate raug txwv nyob rau hauv Tebchaws Meskas thiab yog ua los ntawm kev daws los yog ntawm cov khoom siv polystyrene.

DEAD yog ib qho aza-dienophile thiab tus neeg ua haujlwm dehydrogenating zoo, hloov cov cawv rau aldehydes, thiols rau disulfides thiab hydrazo pawg rau azo pawg; nws kuj yog ib tug zoo electron txais. Thaum DEAD siv ntau cov tshuaj tiv thaiv, nws feem ntau hu ua lub ntsiab lus tseem ceeb ntawm cov tshuaj tiv thaiv Mitsunobu, uas niaj hnub ua hauv cov chaw kuaj tshuaj, thiab tuaj yeem siv rau kev sib txuas ntawm ntau yam khoom ntuj tsim thiab tshuaj. Tshwj xeeb, cov txiaj ntsig tshuaj zidovudine yog cov tshuaj tseem ceeb tiv thaiv AIDS thiab FdUMP yog cov tshuaj tiv thaiv kab mob muaj zog, kuj yog procarbazine, MAOI tsis tuaj yeem.

Yog tias koj txaus siab rau peb cov khoom lossis muaj lus nug, thov koj xav tiv tauj peb!

Cov khoom raws li patent muaj rau R& D lub hom phiaj nkaus xwb. Txawm li cas los xij, lub luag haujlwm kawg tsuas yog nrog tus neeg yuav khoom.
