Izakhiwo Zomzimba Nezamakhemikhali	(s) -3-hydroxy-gamma butyrolactone uketshezi olungenambala, oluncibilika emanzini, utshwala nezinye izincibilikisi eziphilayo, ezingancibiliki ku-petroleum ether, njll., luyi-organic synthesis intermediates ebaluleke kakhulu, futhi luwumthombo obaluleke kakhulu we ububele. Isetshenziswa kakhulu njengesihluthulelo esimaphakathi se-Modulator (R)-gamma-hydroxy-beta-Q hydroxybutyric acid [(R)-GABOB],(R)-GABOB isetshenziselwa ukwelapha i-hyperlipidemia;(ama)-I-Oxiracetam ingumgqugquzeli wobuchopho umzimba, kodwa futhi synthesis yayo; Ukunciphisa kwayo kungatholakala (s) -3-hydroxytetrahydrofuran, okuyindawo ebalulekile yokwelashwa kwezidakamizwa ze-AIDS; i-(s)-3-hydroxy-4-bromobutyric acid ehlanganiswe kuyo iyisiqiniseko esingaba khona; Iguqulwa ibe (s) -5-hydroxymethyl-1, 3-oxazolin-2-one etholakalayo esizukulwaneni sakamuva semithi elwa namagciwane; Ngaphezu kwalokho,(ama)-n-methyl-3-hydroxypyrrole kanye (R)–N-methyl -3-methyl-pyrrole nawo anomsebenzi obalulekile wokuphila komzimba, nawo angatholwa ngokuguqulwa okulula kwe (s) -3-hydroxy- i-gamma butyrolactone. Imikhiqizo eminingi yemvelo ingabuye yenziwe kusuka ku-(s)-3-hydroxy-γbutyrolactone.

Isingeniso

(S) -3-hydroxy-γ-butyrolactone inhlanganisela yezinto eziphilayo. Iwuketshezi olungenambala olunokunambitheka okumnandi, okunezithelo.

Kunezindlela eziningana zokulungiselela i-(S) -3-hydroxy-γ-butyrolactone, evame ukutholwa yi-catalytic hydrogenation. Indlela ethize iwukusabela inani elifanele le-γ-butyrolactone nge-catalyst (efana ne-copper-lead alloy) ekushiseni okufanelekile nokucindezela, futhi ngemva kwe-catalytic hydrogenation, (S) -3-hydroxy-γ-butyrolactone itholakala.

Ulwazi Lokuphepha: (S)-3-hydroxy-γ-butyrolactone inobuthi obuphansi ngaphansi kwezimo zokusetshenziswa okuvamile futhi ayiyona ikhemikhali eyingozi. Ukunakekela kufanele kuthathwe ukuze ugweme ukuthintana nesikhumba, amehlo, nokuphefumula ngesikhathi sokusetshenziswa. Uma uthintana ngephutha, hlambulula ngamanzi futhi ufune usizo lwezokwelapha kusenesikhathi. I-compound kufanele igcinwe kude nendawo yokushisa kanye nezinga lokushisa eliphezulu, futhi igweme ukuthintana nama-oxidants nama-asidi. Ngaphezu kwalokho, kufanele isetshenziswe ngokuhambisana nezinqubo ezifanele zokusebenza kanye nezinyathelo zokusebenza eziphephile.
