Daim ntawv thov:

4-Dimethylaminopyridine (DMAP) (CAS: 1122-58-3) yog ib qho kev ua tau zoo tshiab catalyst dav siv hauv tshuaj synthesis.Nws muaj peev xwm catalytic siab nyob rau hauv cov organic synthesis, tshuaj synthesis, tshuaj tua kab, dye, tshuaj tsw qab synthesis ntawm acylation, alkylation, etherification thiab lwm yam tshuaj, thiab muaj ib tug heev pom tseeb nyhuv ntawm kev txhim kho yield.Acylation ntawm cawv;Acylation ntawm phenols;Acylation ntawm amines;Acylation ntawm enolates;Cov tshuaj tiv thaiv ntawm isocyanates;Lwm yam kev siv;Hloov cov pab pawg ua haujlwm.
DMAP, yog super nucleophilic acylation catalyst.Lub resonance ntawm electron-pab dimethylamino pawg nyob rau hauv nws cov qauv thiab lub nplhaib niam txiv (pyridine nplhaib) tuaj yeem ua kom muaj nitrogen atom ntawm lub nplhaib kom tau txais kev hloov pauv nucleophilic, uas ua rau muaj kev ua haujlwm siab, tsis tshua muaj cawv thiab amines / acids. ntawm acylation / esterification cov tshuaj tiv thaiv yog li 104 ~ 106 npaug ntawm pyridine.Kev hloov pauv Acyl yog ib qho kev hloov pauv hauv cov xwm txheej thiab cov organic synthesis, uas chiral DMAP yog ib qho asymmetric acyl hloov catalyst.Txij li thaum xyoo 1996, Vedejs thiab Fu pab neeg tau tshaj tawm lub hauv paus chiral thiab planar chiral DMAP catalysts feem, chiral DMAP catalysts tau tsim zoo heev.Ntau yam hauv nruab nrab chiral, planar chiral, spiro chiral thiab central chiral DMAP tau tshaj tawm ib qho tom qab, thiab tau siv zoo hauv ntau qhov kev hloov pauv asymmetric acyl.
DMAP yog ntau yam nucleophilic catalyst rau acylation cov tshuaj tiv thaiv thiab esterifications.Nws kuj tseem ua haujlwm nyob rau hauv ntau yam kev hloov pauv hauv cov organic xws li Baylis-Hillman cov tshuaj tiv thaiv, Dakin-West cov tshuaj tiv thaiv, kev tiv thaiv amines, C-acylations, silylations, kev siv hauv cov khoom ntuj tsim tshuaj, thiab ntau lwm tus.
DMAP tuaj yeem siv los ua cov khoom siv hluav taws xob: Rau acylation ntawm alcohols nrog acid anhydrides nyob rau hauv pab pawg- thiab hnyav-dawb tej yam kev mob rau synthesize coj esters.Nyob rau hauv Baylis-Hillman cov tshuaj tiv thaiv los tsim cov pa roj carbon-carbon daim ntawv cog lus los ntawm kev sib txuas ntawm ib qho activated alkene nrog ib qho aldehyde lossis ketone.
Ib qho zoo heev catalyst rau acylation cov tshuaj tiv thaiv.
