1,2,3,4-Di-O-Isopropylidene-alpha-D-galactopyranose CAS:4064-06-6

I-1,2:3,4-Di-O-isopropylidene-D-galactopyranose iyinhlanganisela yamakhemikhali eyingxenye yomndeni we-galactopyranose derivatives. Ivame ukusetshenziswa kumakhemikhali e-organic njenge-ejenti yokuvikela amaqembu e-hydroxyl akhona kushukela, ikakhulukazi i-galactose. Le nhlanganisela yenziwa ngokuphendula i-D-galactose ne-acetone ukuze kwakheke i-diacetone derivative, bese iphathwa nge-asidi ukuze kwakheke i-di-O-isopropylidene derivative. Le derivative ivikela amaqembu e-hydroxyl, ivimbele ukusabela okungafuneki ngesikhathi sokwenziwa kwamakhemikhali, futhi ingasuswa ngokukhetha ukuze kuphinde kukhiqizwe inhlanganisela yokuqala. Isakhiwo sayo esiqinile kanye nokuqina kwayo kwenza kube nenzuzo ezisetshenzisweni ezahlukene emkhakheni wokwenziwa kwezinto eziphilayo.

Ukusetshenziswa kanye Nomphumela

Umphumela oyinhloko we-1,2:3,4-Di-O-isopropylidene-D-galactopyranose ukuvikela amaqembu e-hydroxyl ku-molecule ye-galactose. Lokhu kufezwa ngokwakha i-acetal derivative ejikelezayo, evimba ukusabela kwamaqembu e-hydroxyl. Ukusetshenziswa okukodwa kwale nhlanganisela kusekhemistri yama-carbohydrate kanye nokwakheka. Ngokuvikela amaqembu e-hydroxyl, i-1,2:3,4-Di-O-isopropylidene-D-galactopyranose ivumela ukusabela okukhethayo kwamanye amaqembu asebenzayo, ngaphandle kokusabela okungafuneki ezikhundleni ze-hydroxyl. Lokhu kuvumela ukuphathwa kahle kanye nokuguqulwa kwe-molecule ye-galactose. Ngaphezu kwalokho, le derivative ingasetshenziswa ekwakhiweni kwemikhiqizo ehlukahlukene yemvelo kanye nemithi equkethe izingxenye ze-galactose. Isiza ekwakhiweni kwama-molecule ayinkimbinkimbi, lapho kudingeka khona ukusabela okulawulwayo nokukhetha. Ngaphezu kwalokho, le nhlanganisela inezicelo ekukhiqizweni kwamakhemikhali akhethekile, njenge-surfactants nama-polymers, lapho kudingeka khona ukuguqulwa okuthile kwama-molecule asekelwe ku-galactose. Sekukonke, ukusetshenziswa kwe-1,2:3,4-Di-O-isopropylidene-D-galactopyranose njenge-ejenti evikelayo kwenza ukuhlanganiswa nokuguqulwa okuphumelelayo kwama-compound aqukethe i-galactose emikhakheni eyahlukahlukene, kufaka phakathi i-organic chemistry, imithi, kanye nesayensi yezinto zokwakha.
