Intshayelelo

(S)-( ) -2-Amino-1-butanol yi-organic compound kunye ne-chemical formula C4H11NO. I-molecule ye-chiral ene-enantiomers ezimbini, apho (S) - ( ) -2-Amino-1-butanol enye.

 

(S)-( )-2-Amino-1-butanol lulwelo olungenambala kunye nevumba elibi. Iyanyibilika emanzini kunye nezinyibilikisi eziqhelekileyo zezinto eziphilayo ezifana ne-alcohols kunye ne-ethers.

 

Ukusetyenziswa okubalulekileyo kwale khompawundi kufana ne-chiral catalyst. Ingasetyenziselwa kwi-catalysis ye-asymmetric kwiimpendulo ze-organic synthesis, ezifana ne-asymmetric synthesis ye-amines kunye ne-synthesis ye-chiral heterocyclic compounds. Ikwaluncedo njengendawo ephakathi kwi-synthesis yeziyobisi.

 

Indlela yokulungiselela (S)-( )-2-Amino-1-butanol ibandakanya iindlela ezimbini eziphambili. Enye kukufumana i-aldehyde nge-carbonylation ye-carboxylic acid okanye i-ester, ethi emva koko iphendule nge-ammonia ukufumana imveliso efunekayo. Enye kukufumana i-butanol ngokusabela i-hexanedione nge-refluxing magnesium etywaleni, kwaye emva koko ufumane imveliso ekujoliswe kuyo ngokusabela kokunciphisa.

 

Ezinye izilumkiso zokhuseleko kufuneka zithathelwe ingqalelo xa usebenzisa kwaye ugcina (S)-( )-2-Amino-1-butanol. Lulwelo olunokutsha kwaye kufuneka lugcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu. Izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu zekhemikhali kunye nezibuko, ziyafuneka ukuze zisetyenziswe. Kuphephe ukudibana nolusu kunye nokuphefumla umphunga walo. Ukulahlwa kuyadingeka ngokuhambelana nemigaqo yokulahlwa kwenkunkuma yendawo.
