4-Dimethylaminopyridine (DMAP) (CAS: 1122-58-3) o se faʻamalosi fou sili ona lelei e faʻaaogaina lautele i vailaʻau faʻasolosolo.O loʻo i ai le malosi maualuga o le catalytic i le faʻaogaina o meaola, faʻasologa o vailaʻau, vailaʻau faʻamaʻi, vali, manogi manogi o le acylation, alkylation, etherification ma isi ituaiga o tali, ma e iai sona aafiaga manino i le faʻaleleia o fua.Acylation o le ava malosi;Acylation o phenols;Acylation o amine;Acylation o enolates;Tali a isocyanates;Talosaga Eseese;Fa'aliliuina o Vaega Fa'atino.
DMAP, o se super nucleophilic acylation catalyst.O le resonance o le electron-donating dimethylamino vaega i lona fausaga ma le mama matua (pyridine mama) e mafai ona malosi faʻagaoioia le nitrogen atom i luga o le mama e faʻafeiloaʻi ai le nucleophilic substitution, lea e matua faʻamalosia ai le maualuga o le teteʻe, maualalo-reactive alcohols ma amines / acids Le gaioiga. o le acylation / esterification tali e tusa ma le 104 ~ 106 taimi o le pyridine.Acyl transfer o se suiga masani i le natura ma le faʻaogaina o meaola, lea o le chiral DMAP o se faʻasologa masani asymmetric acyl transfer catalyst.Talu mai le 1996, Vedejs ma Fu 'au na lipotia le ogatotonu chiral ma planar chiral DMAP catalysts faasologa, chiral DMAP catalysts ua matua atiina ae.Ole tele ole chiral tutotonu, planar chiral, spiro chiral ma central chiral DMAP ua lipotia tasi ma le isi, ma ua lelei ona faʻaogaina i le tele o asymmetric acyl transfer reactions.
O le DMAP o se faʻamalosi nucleophilic sili ona lelei mo gaioiga faʻafefe ma esterifications.O loʻo faʻaaogaina foi i suiga eseese o meaola e pei o le Baylis-Hillman reaction, Dakin-West reaction, puipuiga o amine, C-acylations, silylations, talosaga i mea faʻalenatura kemisi, ma le tele o isi.
E mafai ona fa'aogaina le DMAP e fai ma fa'amalosi: Mo le acylation o 'ava mālosi fa'atasi ai ma acid anhydride i lalo o fa'avae fesoasoani- ma tulaga e leai se solvent e fa'apipi'i ai esters tutusa.I le tali a Baylis-Hillman e fausia ai le carbon-carbon bond e ala i le fa'apipi'iina o se alkene fa'agaoioia ma se aldehyde po'o le ketone.
O se faʻamalosi sili ona lelei mo gaioiga acylation.
