Isingeniso

(S)-( )-2-Amino-1-butanol iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C4H11NO. Kuyi-molecule ye-chiral enama-enantiomers amabili, okuthi (S)-( )-2-Amino-1-butanol eyodwa.

 

(S)-( )-2-Amino-1-butanol uketshezi olungenambala olunephunga elimnandi. Iyancibilika emanzini nasezincibilikisini ezivamile ezifana notshwala nama-ether.

 

Ukusetshenziswa okubalulekile kwalesi sakhi kunjenge-catalyst ye-chiral. Ingasetshenziswa ku-catalysis ye-asymmetric ekuphenduleni kwe-organic synthesis, njenge-asymmetric synthesis yama-amine kanye nokuhlanganiswa kwe-chiral heterocyclic compounds. Kuwusizo futhi njengesimaphakathi ekuhlanganiseni izidakamizwa.

 

Indlela yokulungiselela (S)-( )-2-Amino-1-butanol ihlanganisa imizila emibili emikhulu. Enye iwukuthola i-aldehyde ngokufaka i-carbonylation ye-carboxylic acid noma i-ester, ebe isabela nge-ammonia ukuze kutholwe umkhiqizo owufunayo. Okunye ukuthola i-butanol ngokusabela i-hexanedione nge-magnesium eshintshayo otshwaleni, bese uthola umkhiqizo oqondiwe ngokusabela kokunciphisa.

 

Ezinye izinyathelo zokuphepha zidinga ukunakwa lapho usebenzisa futhi ugcina (S)-( )-2-Amino-1-butanol. Iwuketshezi oluvutha umlilo futhi idinga ukubekwa kude namalangabi avulekile kanye namazinga okushisa aphezulu. Izimpahla zokuzivikela ezifanele, njengamagilavu ​​amakhemikhali nezibuko, ziyadingeka ukuze zisetshenziswe. Gwema ukuthinta isikhumba kanye nokuhogela umhwamuko waso. Ukulahlwa kuyadingeka ngokuhambisana nemithetho yendawo yokulahlwa kwemfucuza.

    • Bhala umyalezo wakho lapha futhi usithumelele wona
