Application:

4-Dimethylaminopyridine (DMAP) (CAS: 1122-58-3) chinhu chitsva chekugadzirisa zvakanyanya chinoshandiswa zvakanyanya mumakemikari synthesis.Iyo ine yakakwira catalytic kugona mune organic synthesis, dhizaini synthesis, mushonga wezvipembenene, dhayi, inonhuhwirira synthesis yeacylation, alkylation, etherification uye mamwe marudzi ekuita, uye ine mhedzisiro iri pachena pakuvandudza goho.Acylation yedoro;acylation ye phenols;Acylation yemamines;Acylation yeanolates;Maitiro e isocyanates;Miscellaneous Applications;Kutamiswa kweMapoka Anoshanda.
DMAP, ndeye super nucleophilic acylation catalyst.Iyo resonance ye electron-donating dimethylamino boka muchimiro chayo uye mhete yemubereki (pyridine ring) inogona kumisa zvakasimba atomu yenitrogen paringi kuti ipinde nucleophilic substitution, iyo inonyanya kukonzeresa kupikisa kwakanyanya, kuderera-reactive alcohols uye amines / acids Chiitiko. yeacylation/esterification reaction inenge 104 ~ 106 nguva yepyridine.Acyl kufambisa ishanduko yakajairika mumasikirwo uye organic synthesis, umo chiral DMAP yakajairika asymmetric acyl kutamisa catalyst.Kubva 1996, Vedejs nechikwata cheFu vakashuma chepakati chiral uye planar chiral DMAP catalysts zvichiteerana, chiral DMAP catalysts dzakagadzirwa zvakanyanya.Yakasiyana-siyana yepakati chiral, planar chiral, spiro chiral uye yepakati chiral DMAP yakashumwa imwe mushure meimwe, uye yakashandiswa zvakanaka mune akawanda asymmetric acyl kutamisa maitiro.
DMAP inogoneka kwazvo nucleophilic catalyst yeacylation reactions uye esterifications.Inoshandiswawo mukuchinja kwakasiyana-siyana kwehupenyu seBaylis-Hillman reaction, Dakin-West reaction, kuchengetedza maamines, C-acylations, silylations, kushandiswa mune zvakasikwa zvigadzirwa chemistry, uye zvimwe zvakawanda.
DMAP inogona kushandiswa sechinhu chinokonzeresa: Kune acylation yezvinwiwa zvine acid anhydrides pasi peyairesi base- uye solvent-isina mamiriro ekugadzira anoenderana esters.MuBaylis-Hillman maitiro ekugadzira kabhoni-kabhoni bond nekubatanidza alkene yakagadziriswa ine aldehyde kana ketone.
Iyo inoshanda zvakanyanya inokonzeresa yeacylation reactions.
