Taw qhiathiab daim ntawv thovntawm CAS No. 609-08-5|Diethyl methylmalonate
Diethyl methylmalonate yog cov organic compound nrog cov tshuaj formula CH3COCH2COOC2H5. Nws yog sodium ntsev ntawm diethyl methylmalonate, uas yog nitrite ion pub. Diethyl methylmalonate tau siv los ua kom lub palladium-catalyzed coupling ntawm alkanoic acids thiab methylmalonic acid nyob rau hauv lub xub ntiag ntawm triethylamine. Cov tshuaj tiv thaiv no hloov cov alkanoic acid rau hauv ester thiab methylmalonic acid rau hauv cawv. Cov txheej txheem tshuaj tiv thaiv rau cov txheej txheem no suav nrog kev hloov pauv cov tshuaj tiv thaiv los ntawm diethyl methylmalonate mus rau alkanoic acid ua raws li kev hloov pauv nucleophilic ntawm carbon atom 2 ntawm alkanocarboxylic acid los ntawm methyll malonyl chloride.
Diethyl methylmalonate tau yooj yim siv los ua ib qho loj loj nucleophile hauv cov organic synthesis. Diethyl methylmalonate kuj tseem siv los ua cov tshuaj reagent los ua ke 7-alkylaminopyrazolo[1,5-a]pyrimidines, cov tebchaw uas muaj cov tshuaj tua kab mob.
