Codsiga:

4-Dimethylaminopyridine (DMAP) (CAS: 1122-58-3) waa kicin wax ku ool ah oo cusub oo si weyn loogu isticmaalo isku dhafka kiimikada.Waxay leedahay awoodda kicinta sare ee isku-dhafka organic, isku-darka daroogada, sunta cayayaanka, dheeha, udgoonka udgoonka ee acylation, alkylation, etherification iyo noocyada kale ee falcelinta, waxayna leedahay saameyn aad u muuqata oo ku saabsan hagaajinta dhalidda.Acylation ee khamriga;Acylation of phenols;Acylation ee amines;Dhaqdhaqaaqa enolate;Falcelinta isocyanates;Codsiyada kala duwan;Wareejinta Kooxaha Waxqabadka
DMAP, waa kicinta acylation nucleophilic super.Dhawaaqa kooxda dimethylamino-ku-deeqaha elektaroonigga ah ee qaab-dhismeedkeeda iyo giraanta waalidka (giraanta pyridine) waxay si xoog leh u kicin kartaa atamka nitrogen ee giraanta si uu u maro beddelka nucleophilic, taas oo si weyn u kicinaysa iska caabbinta sare, alkolada falcelis yar iyo amines / acids Dhaqdhaqaaqa falcelinta acylation/esterification waxay ku saabsan tahay 104 ~ 106 jeer marka loo eego pyridine.Wareejinta Acyl waa isbeddel caadi ah oo ku yimaada dabeecadda iyo isku-dhafka noolaha, kaas oo chiral DMAP uu yahay kicinta wareejinta acyl-ka caadiga ah.Laga soo bilaabo 1996, kooxda Vedejs iyo Fu waxay ka warbixiyeen kicinta dhexe ee chiral iyo planar chiral DMAP siday u kala horreeyaan, kiciyaasha chiral DMAP ayaa si weyn loo horumariyay.Chiral dhexe oo kala duwan, planar chiral, spiro chiral iyo chiral dhexe DMAP ayaa la soo sheegay midba midka kale, waxaana si wanaagsan loo dabaqay falcelino badan oo kala wareejinta asymmetric acyl.
DMAP waa kicinta nucleophilic oo aad isku dhafan oo loogu talagalay falcelinta acylation-ka iyo caddaymaha.Waxa kale oo lagu shaqaaleysiiyay isbeddello dabiici ah oo kala duwan sida falcelinta Baylis-Hillman, falcelinta Dakin-West, ilaalinta amines, C-acylations, silylations, codsiyada kiimikooyinka dabiiciga ah, iyo kuwo kale oo badan.
DMAP waxa loo isticmaali karaa kiciyayaal ahaan: Soo kicinta alkolada leh anhydrides aashitada oo hoos timaada saldhig caawimo- iyo xaalado aan dareere lahayn si loo soo saaro esters u dhigma.Gudaha Baylis-Hillman falcelinta si loo sameeyo curaarta kaarboon-carbon iyadoo la isku xirayo alkene firfircoon iyo aldehyde ama ketone.
Dajiye wax ku ool ah oo heer sare ah oo kicinaya falcelinta acylation.
