Methyl 4-O-benzyl-α-l-rhamnopyranoside
In the title compound, C14H20O5, an inter-mediate in the synthesis of oligosaccharides, the glycosidic [H-C-O-C(H3)] torsion angle ϕH is 52.3° and the exo-cyclic [H-C-O-C(H2)] torsion angle θH is -11.7°. The hexa-pyran-ose ring has a chair conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains propagating along [010]. Enclosed within the chains are R 3 (3)(1...
متن کاملCrystal structure of O-benzyl-l-tyrosine N-carboxy anhydride
In the title compound, C17H15NO4 (alternative name; O-benzyl-l-tyrosine N-carb-oxy anhydride), the oxazolidine ring is planer, with an r.m.s. deviation of 0.039 Å. The benz-yloxy and benzyl rings are almost coplanar, making a dihedral angle of 0.078 (10)°, and are inclined to the oxazolidine ring by 59.16 (11) and 58.42 (11)°, respectively. In the crystal, mol-ecules are linked by N-H⋯O and C-H...
متن کامل1-O-Acetyl-3,4,6-tri-O-benzyl-2-C-bromomethyl-2-deoxy-α-d-glucopyranose
In the title compound, C30H33BrO6, the pyran-ose ring adopts a chair conformation. Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1 (2) and 64.6 (2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.9 (2)° to this C/C/C/O plane. Th...
متن کاملRat liver L-threonine dehydrogenase.
L-threonine dehydrogenase (E.C.1.1.1.103) catalyzes the NAD+-dependent transformation of Lthreonine to 2-amino 3-0x0-butyric acid, which spontaneously loses CO2 with the final production of aminoacetone ( 1) The enzyme is present in several microorganisms as well as in the liver of vertebrates (2-6). We studied some properties of the rat liver enzyme, showing that the activity was strongly inhi...
متن کامل2-Acetamido-N-benzyl-1,4-imino-1,2,4-trideoxy-l-xylitol (N-benzyl-l-XYLNAc)
X-ray crystallography defines the relative configuration at the three-stereogenic centres in the title compound N-benzyl-l-XYLNAc, C(14)H(20)N(2)O(3). The five-membered pyrrolidine ring adopts an envelope conformation with the N atom lying out of the plane of the other four atoms. In the crystal structure, inter-molecular O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonds link the mol-ecules into chains alo...
