6-Azido-6-deoxy-α-l-galactose (6-azido-l-fucose) monohydrate
Although 6-azido-6-de-oxy-l-galactose in aqueous solution is in equilibrium between the open-chain, furan-ose and pyran-ose forms, it crystallizes solely as 6-azido-6-de-oxy-α-l-galactopyran-ose monohydrate, C(6)H(11)N(3)O(5)·H(2)O, with the six-membered ring adopting a chair conformation. The structure exists as hydrogen-bonded chains, with each mol-ecule acting as a donor and acceptor of five...
متن کاملMethyl 6-azido-6-deoxy-α-d-galactoside
The structure of the title compound, C(7)H(13)N(3)O(5), was solved using data from a multiple fragment crystal. The galactoside ring adopts a (4)C(1) chair conformation. In the crystal, the molecules are linked by strong O-H⋯O hydrogen bonds, which build linkages around the screw axis of the cell in a similar way to the iodo analogue. These C-5 and C-6 packing motifs expand to R(2) (2)(10), C(2...
متن کاملDimerization of propargyl and homopropargyl 6-azido-6-deoxy-glycosides upon 1,3-dipolar cycloaddition
Copper-catalyzed, thermal or microwave promoted 1,3-dipolar cycloaddition (Click Reaction) of 2-propynyl and 3-butynyl 2,3,4-tri-O-acetyl-6-azido-6-deoxy-glycopyranosides in the D-gluco, D-galacto and D-manno series afford the corresponding dimeric cycloaddition products.
متن کامل4-Azido-2-chloro-6-methylquinoline
In the title compound, C(10)H(7)ClN(4), the quinoline ring system is planar [maximum deviation 0.0035 (10) Å]. The crystal structure is stabilized by van der Waals and π-π stacking inter-actions [centroid-centroid distance 3.6456 (17) Å].
متن کامل6-Deoxy-α-l-talopyranose
X-ray crystallography showed that the title compound, C(6)H(12)O(5), crystallizes in the α-pyran-ose form with the six-membered ring in a chair conformation. The crystal structure exists as a three-dimensional hydrogen-bonded network of mol-ecules with each mol-ecule acting as a donor and aceptor for four hydrogen bonds. The absolute configuration was determined by the use of l-fucose as starti...
