Taupānga:

Ko te 4-Dimethylaminopyridine (DMAP) (CAS: 1122-58-3) he whakakorikori tino pai hou e whakamahia nuitia ana i roto i te whakahiato matū.He kaha catalytic tiketike i roto i te kōtuitanga waro, te kōtuitanga tarukino, pesticide, tae, kakara kōtuitanga o acylation, alkylation, etherification me ētahi atu momo o te tauhohenga, a he tino kitea pānga ki te whakapai ake i tukua.Acylation o te waipiro;Acylation o phenols;Acylation o amine;Acylation o enolates;Nga tauhohenga o te isocyanates;Nga momo tono;Whakawhitinga Rōpū Mahi.
Ko te DMAP, he whakakorikori acylation nucleophilic super.Ko te resonance o te roopu dimethylamino koha irahiko i roto i tona hanganga me te mowhiti matua (te mowhiti pyridine) ka kaha te whakahohe i te ngota hauota i runga i te mowhiti ki te tango i te whakakapi nucleophilic, e tino whakakorikori ana i te aukati teitei, nga waipiro iti-reactive me nga amine/waikawa Ko te mahi. o te tauhohenga acylation/esterification he tata ki te 104~106 nga wa o te pyridine.Ko te whakawhitinga Acyl he huringa noa i roto i te taiao me te whakahiato waro, i roto i te chiral DMAP he whakakorikori whakawhiti acyl hangarite noa.Mai i te tau 1996, i ripoatahia e te roopu Vedejs me Fu te puku o te puku o te puku me te whakakini DMAP chiral planar, kua tino whakawhanakehia nga kaiwhakatuma chiral DMAP.He maha nga tohu o te pokapū, te planar chiral, te spiro chiral me te DMAP chiral pokapū kua korerohia tetahi i muri i tetahi, a kua pai te whakamahi i roto i te maha o nga tauhohenga whakawhiti acyl asymmetric.
Ko te DMAP he whakakorikori nucleophilic tino pai mo nga tauhohenga acylation me te whakaeteropi.Ka whakamahia ano hoki i roto i nga momo panoni rauropi penei i te tauhohenga a Baylis-Hillman, te tauhohenga Dakin-West, te whakamarumaru o nga amine, C-acylations, silylations, tono i roto i nga hua matū matū, me te maha atu.
Ka taea te whakamahi i te DMAP hei whakakorikori: Mo te acylation o nga waipiro me te waikawa anhydride i raro i nga tikanga awhina-kore me te whakarewa-kore ki te whakahiato i nga hākawa e rite ana.I roto i te tauhohenga Baylis-Hillman ki te hanga i te here waro-wao ma te hono o te alkene whakahohe me te aldehyde, ketone ranei.
He whakakōkī tino pai mō ngā tauhohenga acylation.
