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

ʻO ka hopena nui o ka 1,2: 3,4-Di-O-isopropylidene-D-galactopyranose e pale i nā hui hydroxyl ma ka mole galactose.Hoʻokō ʻia kēia ma ka hana ʻana i kahi derivative cyclic acetal, kahi e poloka ai i ka reactivity o nā hui hydroxyl.Ma ka pale ʻana i nā pūʻulu hydroxyl, hiki i ka 1,2:3,4-Di-O-isopropylidene-D-galactopyranose ke koho koho i nā hui hana ʻē aʻe, me ka ʻole o nā hopena makemake ʻole ma nā kūlana hydroxyl.ʻAe kēia i ka hoʻololi ʻana a me ka hoʻololi ʻana o ka molegalactose.Kōkua ia i ke kūkulu ʻana i nā molekala paʻakikī, kahi e koi ʻia ai nā hopena hoʻomalu a koho. ka hoʻohana ʻana i ka 1,2:3,4-Di-O-isopropylidene-D-galactopyranose ma ke ʻano he mea pale e hiki ai i ka synthesis maikaʻi a me ka hoʻololi ʻana o nā pūhui i loaʻa i ka galactose ma nā ʻano ʻano like ʻole, me ka kemika organik, nā lāʻau lapaʻau, a me nā ʻepekema waiwai.
