Application of 10343-06-3. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose

Trifluoromethylzinc bromide was used to prepare the corresponding glycosyl fluorides from the peracetylated alpha-pyranosyl bromides of D-glucose 1, D-galactose 3, D-mannose 5, D-lyxose 7, and L-rhamnose 9, respectively, in good yields. D-Glucopyranosyl bromide 1 and the D-galactopyranosyl bromide 3, exclusively delivered the corresponding beta-D-glycosyl fluorides 2beta and 4beta. The other bromides 5, 7 and 9 formed mixtures of anomeric fluorides (6alpha/6beta, 8alpha/8beta, 10alpha/10beta). Similarily, the anomeric OH-groups of the D-glycopyranoses 11, 12, 13, 15, 17 could be substituted by fluoride using trifluoromethylzinc bromide/titanium tetrafluoride. In all cases mixtures of anomeric fluorides 2alpha/2beta, 6alpha/6beta, 14alpha/14beta, 16alpha/16beta, and 18alpha/18beta were obtained.

Synthetic Route of 10343-06-3. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose

An efficient and convenient synthetic route to glycosyl 1-beta-phosphates has been developed using diallyl chlorophosphate as a phosphorylating agent with 4-N,N-dimethylaminopyridine under mild conditions. Diallyl-glycosyl 1-beta-phosphate triesters of d-manno, l-glycero-d-manno-hepto-, d-gluco-, d-galacto-, and l-fuco-pyranose as well as lactose have been obtained by this strategy in good yields and excellent beta-selectivities. Furthermore, the diallyl 6-azido-mannosyl 1-beta-phosphate 2 was deprotected under mild conditions and converted into potentially clickable analogues of beta-mannosyl phosphoisoprenoids I and ADP-heptose II.

Compound 2 crystallises in the triclinic system, space group P1?. The lattice constants are a=8.1616(5), b=9.4156(6), c=10.2921(6) A, alpha=72.58(2), beta=72.48(4), gamma=73.19(2) with Z=1 and R1=0.0595. Crystals of 3 are orthorhombic with space group Cmc21. The lattice constants are a=15.979(1), b=8.550(1), c=18.237(1) A with Z=4 and R=0.0623. Compound 1 contains a dinuclear [Br(dpyam)Cu(OH)2Cu(dpyam)Br] unit with a dihedral angle between the CuO2 planes of 179.9. Each copper atom is in a square-pyramidal coordination environment; the basal plane consists of two bridging hydroxo groups and two dpyam ligands coordinated through their nitrogen atom. The fifth axial coordination site of each copper(II) ion is occupied by a Br atom, at a weak semi-coordination distance of 2.803(2) and 2.804(2) A. For compound 2, the coordination geometry around each copper(II) ion is distorted elongated octahedral, CuN2O4. The equatorial positions are occupied by the two nitrogen atoms of dpyam and the two oxygen atoms of the bridging hydroxo groups, where the apical positions are occupied by oxygen atoms from both triflate groups. In the dinuclear units of compound 3 the triply-bridged Cu(II) ions show a distorted square pyramidal coordination. The fifth apical ligand is a longer bonded bridging water molecule for 3, at distances of 2.220(2) A, which joins the basal CuN2O2 planes in a roof-shaped configuration (dihedral angle 135.8o). The Cu-Cu distances are 2.993(2), 2.964(2) and 2.849(2) A for compounds 1, 2 and 3, respectively. The magnetic susceptibility measurements revealed a ferromagnetic interaction between the Cu(II) atoms for compound 2, with a singlet-triplet energy gap (J) around 83 cm-1. Compound 1 has an antiferromagnetic interaction with a J of -48.6 cm-1, whereas compound 3 is very weakly antiferromagnetic with J=-0.6 cm-1.
