Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations.74808-09-6, Name is (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate, molecular formula is C36H36Cl3NO6.

Glycosidation of the myo-inositol derivatives 2 and 3 by the diazirine 1 yields 90percent of a diastereoisomer pair of beta-D-glycosides in a 1:1 ratio, i.e. 5/6 and 7/8, respectively (Scheme 1).The crystal structure of 3 shows a strong intramolecular H-bond, which persists in solution, as indicated by FT-IR and 1H-NMR spectra.Yields and diastereoselectivity are lower for the glycosidation of 24 by 1 (Scheme 3).The resulting 1,2- and 1,4-linked disaccharides 25-28 were isolated as their acetates 29-32.The previously determined crystal structure of 24 shows no intramolecular H-bonds.The yield of the glycosidation of 24, but not of 3, depends upon the concentration, indicating that activation of 24 by intermolecular H-bonds is required.Glycosidation of 2 and 3 with the trichloroacetimidate 14 gave mixtures of four (5, 6, 15, and 16), and six (7, 8, and 17-20) disaccharides, respectively (Scheme 2).
