Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. Like 10034-20-5, Name is (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride. In a document type is Article, introducing its new discovery. Application of 10034-20-5
3,4,6-Tri-O-acetyl-2-deoxy-2-trichloroacetamido-alpha-D-glucopyranosyl trichloroacetimidate and its O-benzylated analogue were tested as glycosyl donors in the reaction with a set of sugar acceptors unsubstituted on O-3 and O-4, typically encountered in the synthesis of oligosaccharides.Glycosides were obtained in good to excellent yields with only a slight excess (1.1-1.2 equiv) of the donor, and with a high degree of 1,2-trans stereoselectivity.The corresponding 2-(trichloromethyl)oxazolinium ion was postulated to be the major reactive intermediate.The N-trichloroacetyl groups in the disaccharide products were easily transformed into N-acetyl under neutral conditions by reduction with tributylstannane.
