2,3,4,6-Tetra-O-acetyl-a-D-galactopyranosyl 2,2,2-trichloroacetimidate jẹ kemikali kemikali ti o wọpọ ti a lo ninu kemistri carbohydrate ati awọn aati glycosylation.O jẹ itọsẹ ti α-D-galactopyranose, iru gaari kan, nibiti awọn ẹgbẹ hydroxyl lori awọn ipo 2, 3, 4, ati 6 ti iwọn galactopyranose jẹ acetylated.Ni afikun, erogba anomeric (C1) ti suga jẹ aabo pẹlu ẹgbẹ trichloroacetimidate, eyiti o jẹ ki o jẹ elekitirofili to lagbara lakoko awọn aati glycosylation.
Apọpọ naa ni a maa n lo gẹgẹbi oluranlowo glycosylating lati ṣafihan awọn ẹya galactose sinu ọpọlọpọ awọn ohun elo, gẹgẹbi awọn ọlọjẹ, awọn peptides, tabi awọn ohun elo Organic kekere.Eyi le ṣe aṣeyọri nipa didaṣe adaṣe yii pẹlu nucleophile (fun apẹẹrẹ, awọn ẹgbẹ hydroxyl lori moleku ibi-afẹde) labẹ awọn ipo to dara.Ẹgbẹ trichloroacetimidate n ṣe irọrun isomọ ti awọn nkan galactose si molikula ibi-afẹde, ti o fa idasile ti mnu glycosidic kan.
Apọpọ yii jẹ lilo nigbagbogbo ni iṣelọpọ ti glycoconjugates, glycopeptides, ati glycolipids.O funni ni ọna ti o wapọ ati lilo daradara fun iyipada awọn ohun elo pẹlu awọn iṣẹku galactose, eyiti o le ṣe pataki ni awọn aaye pupọ, pẹlu awọn ẹkọ ẹkọ ti ibi, awọn eto ifijiṣẹ oogun, tabi idagbasoke ajesara.
