Synthesis of L-sugars from 4-deoxypentenosides.
[reaction: see text] 4-Deoxypentenosides, which are readily derived from D-sugars, resemble glycals in structure and reactivity and can undergo stereoselective epoxidation and S(N)2 nucleophilic addition to produce L-sugars in pyranosidic form.
متن کاملThymidine Diphosphate 4-acetamido-4, 6-dideoxyhexoses. I. Enzymatic Synthesis by Strains of Escherichia Coli.
Several thymidine diphosphate sugar compounds have been isolated from Escherichia coli strains and other microorganisms. TDP-X, isolated from E. coli strain Y-10 by Strominger and Scott (1) and from other strains of E. coli (2) and TDP-X2 isolated from E. coli strain B, by Okazaki, Okazaki, and Kuriki (3) are unusual acetamido sugar-containing nucleotides (4). The sugars are 4-acetamido-4,6-did...
متن کامل4-Acetamido-3-nitrophenyl acetate
In the mol-ecule of the title compound, C(10)H(10)N(2)O(5), intra-molecular C-H⋯O inter-actions result in the formation of a five- and a six-membered ring. The five-membered ring is planar and is oriented at a dihedral angle of 0.34 (3)° with respect to the plane of the aromatic ring, while the six-membered ring has a twist conformation. In the crystal structure, inter-molecular C-H⋯O inter-act...
متن کاملIndium-mediated allylation in carbohydrate synthesis: A short and efficient approach towards higher 2-acetamido-2-deoxy sugars
Higher aminosugars are interesting targets in carbohydrate synthesis since these compounds play important roles in biological systems. However, their availability from natural sources is limited. Thus, in order to investigate their biological function, the development of facile and adaptable routes to this class of compounds is of fundamental importance. Our synthetic route towards these target...
متن کاملSynthesis and Properties of Selected 4-Substituted Anhydro Sugars
A new class of 4-deoxy-4-([4-substituted-l-piperazinyl], [4-morpholinyl] and [4-(perhydrol,4-thiazin-4-yl)])-2,3-anhydrolyxopyranosides (3a-g and 6a-g) were synthesized from ep oxy triflate moities 2 and 5 and 4-substituted piperazines, morpholines and perhydro-1,4thiazines, respectively, to test their antibacterial activity. The characterized series of new compounds was tested in vitro agains...
