Ntchito:

4-Dimethylaminopyridine (DMAP) (CAS: 1122-58-3) ndi chothandizira chatsopano chomwe chimagwiritsidwa ntchito kwambiri popanga mankhwala.Iwo ali mkulu chothandizira mphamvu mu kaphatikizidwe organic, kaphatikizidwe mankhwala, mankhwala, utoto, fungo kaphatikizidwe wa acylation, alkylation, etherification ndi mitundu ina anachita, ndipo ali ndi zotsatira zoonekeratu pa kuwongolera zokolola.Acylation wa mowa;acylation wa phenols;Acylation wa amine;Acylation wa ma enolates;Zochita za isocyanates;Zosiyanasiyana Mapulogalamu;Kusamutsa Magulu Ogwira Ntchito.
DMAP, ndi chothandizira chachikulu cha nucleophilic acylation.Kumveka kwa gulu la electron-donating dimethylamino mu kapangidwe kake ndi mphete ya kholo (pyridine mphete) imatha kuyambitsa atomu ya nayitrogeni pa mpheteyo kuti ilowe m'malo mwa nucleophilic, yomwe imapangitsa kuti kukana kwambiri, mowa wocheperako komanso ma amines / zidulo. acylation/esterification reaction ndi pafupifupi 104 ~ 106 nthawi ya pyridine.Kutengerapo kwa Acyl ndikusintha kofala kwachilengedwe komanso kaphatikizidwe ka organic, momwe chiral DMAP ndi chothandizira chodziwika bwino cha asymmetric acyl transfer.Kuchokera mu 1996, gulu la Vedejs ndi Fu linanena za zothandizira zapakati pa chiral ndi planar DMAP motsatana, zothandizira za DMAP zachiral zapangidwa kwambiri.Zosiyanasiyana zapakati pa chiral, planar chiral, spiro chiral ndi central chiral DMAP zanenedwapo motsatira, ndipo zagwiritsidwa ntchito bwino pamachitidwe ambiri a asymmetric acyl.
DMAP ndi chothandizira kwambiri cha nucleophilic chothandizira ma acylation reaction and esterifications.Amagwiritsidwanso ntchito pakusintha kwachilengedwe kosiyanasiyana monga Baylis-Hillman reaction, Dakin-West reaction, protection of amines, C-acylations, silylations, applications in natural products chemistry, ndi ena ambiri.
DMAP angagwiritsidwe ntchito ngati chothandizira: Pakuti acylation wa mowa ndi asidi anhydrides pansi wothandiza maziko- ndi zosungunulira-free mikhalidwe kupanga lolingana esters.Mu machitidwe a Baylis-Hillman kupanga chomangira cha kaboni-carbon mwa kuphatikiza alkene yolumikizidwa ndi aldehyde kapena ketone.
Chothandizira kwambiri cha ma acylation reaction.
