ʻO 4-Dimethylaminopyridine (DMAP) (CAS: 1122-58-3) kahi mea hoʻoheheʻe maikaʻi hou i hoʻohana nui ʻia i ka synthesis kemika.Loaʻa iā ia ka mana catalytic kiʻekiʻe i ka synthesis organik, synthesis lāʻau lapaʻau, pesticide, dye, ʻala synthesis o acylation, alkylation, etherification a me nā ʻano ʻano like ʻole, a he hopena maopopo loa i ka hoʻomaikaʻi ʻana i ka hua.Acylation o ka waiʻona;Acylation o nā phenols;Acylation o nā amine;Acylation o nā enolate;Nā pane o nā isocyanates;Nā noi like ʻole;Hoʻololi i nā hui hana.
ʻO DMAP, kahi mea hoʻoheheʻe super nucleophilic acylation.Hiki i ka resonance o ka pūʻulu dimethylamino hāʻawi electron i loko o kona hale a me ke apo makua (pyridine ring) hiki ke hoʻoikaika ikaika i ka atom nitrogen ma ke apo e hana i ka nucleophilic substitution, kahi e hoʻoikaika nui ai i ke kū'ē kiʻekiʻe, haʻahaʻa-reactive alcohols a me nā amine/acids. ʻO ka hopena acylation / esterification ma kahi o 104 ~ 106 mau manawa o ka pyridine.ʻO ka hoʻololi ʻana ʻo Acyl kahi hoʻololi maʻamau i ke ʻano a me ka synthesis organik, kahi chiral DMAP he mea hoʻololi maʻamau asymmetric acyl transfer catalyst.Mai ka makahiki 1996, hōʻike ka hui ʻo Vedejs a me Fu i ke kikowaena chiral a me planar chiral DMAP catalysts, ua hoʻomohala nui ʻia nā chiral DMAP catalysts.Ua hōʻike ʻia nā ʻano chiral waena, planar chiral, spiro chiral a me central chiral DMAP kekahi ma hope o kekahi, a ua hoʻohana maikaʻi ʻia i nā hopena asymmetric acyl transfer.
ʻO DMAP kahi mea hoʻoheheʻe nucleophilic nui loa no nā hopena acylation a me nā esterifications.Hoʻohana ʻia ia i nā loli kūlohelohe like ʻole e like me Baylis-Hillman reaction, Dakin-West reaction, protection of amines, C-acylations, silylations, applications in natural products chemistry, a me nā mea he nui.
Hiki ke hoʻohana ʻia ka DMAP ma ke ʻano he catalyst: No ka acylation o nā ʻawaʻawa me nā anhydride waikawa ma lalo o ke kumu kōkua- a me nā kūlana solvent-free e synthesize esters pili.Ma Baylis-Hillman pane ʻana e hana i ka paʻa kalapona-kāpona ma ka hoʻohui ʻana o kahi alkene i hoʻāla ʻia me kahi aldehyde a i ʻole ketone.
ʻO kahi catalyst maikaʻi loa no nā hopena acylation.
