The total synthesis of D-erythro-sphingosine (9) was performed by a chirospecific method starting from D-galactose via an azidosphingosine intermediate to give highly homogeneous ( > 99.9% C18:1) sphingosine base (9) which contained no observable olefin isomerization by product and was demonstrated to be optically pure by a novel method utilizing Mosher’s acid. Ceramide (10) was prepared from this sphingosine (9) with highly homogeneous (99.8% C16:0) palmitic acid by two methods. The cerebroside glucosylceramide (23) was the next sphingolipid in this series to be synthesized in a highly homogeneous form. These three sphingolipids are currently being used for biophysical studies of the structures of their hydrated bio-molecular assemblies.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals. However, they have proven to be challenging because of the mutual inactivation of both catalysts. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

One-dimensional polymeric or oligomeric chains, in which various linear trinickel complexes linked to the axial sites of metalloporphyrins by the combination of self-assembly and coordination chemistry, have been constructed. A carboxylate group of carboxylpyridine was attached to the end of linear trinickel complexes to produce the linear building blocks, Ni 3(dpa)4X2 [X = 4-PyCOO- (1) or 3-PyCOO- (2)], which was then reacted with metalloporphyrins to form stable polymers or oligomers. The new self-assembled oligomeric chain, [Ni 3(dpa)4(4-PyCOO)2][ZnTPP]2 (3), and two novel self-assembled one-dimensional polymeric chains, {[Ni 3(dpa)4(4-PyCOO)2[MnTPP]}n(ClO 4)n (4), and {[Ni3(dpa)4(3-PyCOO) 2][MnTPP]}n(ClO4)n (5), [dpa – = di(alpha-pyridyl)amido anion; TPP = meso-tetraphenyl- porphyrinato dianion], have been synthesized and their structures were determined by X-ray diffraction. The UV/vis spectra indicate the absence of any noticeable interactions between the linear trinickel units and metalloporphyrins in these chains. The magnetic susceptibility measurements in the solid state show that both polymers 4 and 5 have a very weak ferromagnetic interaction. The Royal Society of Chemistry 2003.

Binary and ternary cobalt(II) complexes involving 2,2?-dipyridylamine and various biologically relevant ligands containing different functional groups are investigated. The ligands used are dicarboxylic acids, amino acids, and DNA unit constituents. The ternary complexes are formed by simultaneous reactions. The results showed the formation of 1:1 complexes with amino acids and dicarboxylic acids. The effect of chelate ring size of the dicarboxylic acid complexes on their stability constants was examined. The stability of ternary complexes formed with dicarboxylic acids was quantitatively compared with their corresponding binary complexes in terms of the a?log 10 K parameters. The concentration distribution of the complexes in solution was evaluated. The solid complexes of Co(II) dipyridylamine cyclobutane-1,1-dicarboxylate, or malonate, oxalate, and succinate have been synthesized and characterized by elemental analysis, infrared spectra, magnetic, and conductance measurements. Spectroscopic studies and M eff values suggest a tetrahedral geometry for the cobalt(II) complexes. The effect of temperature on the formation constant of the complexes was studied, and the thermodynamic parameters were calculated. Formation of the metal complexes has been found to be spontaneous, exothermic, and entropically favorable.

(Chemical Equation Presented) The first O-glycosylation of hydroxamic acids is reported. This process involves the use of glycosyl N-phenyl trifluoroacetimidates as glycosyl donors in the presence TMSOTf and 4 A molecular sieves in dichloromethane. Under such conditions, a wide range of new glycosyl donors including glucosyl, galactosyl, mannosyl, glucuronyl, and ribosyl hydroxamates were prepared in good to high yields. This procedure appears to be an advantageous alternative for the synthesis of glycosyl hydroxamates of biological interest.

A Pd0-catalyzed asymmetric Nazarov-type cyclization is described. The optimized ligand for the reaction incorporates a weakly coordinating pyridine ring into a TADDOL-derived phosphoramidite (TADDOL=alpha,alpha,alpha,alpha-tetraaryl-1,3-dioxolane-4,5-dimethanol). The reaction leads to the formation of cyclopentenones as single diastereoisomers that incorporate two contiguous asymmetric centers, one tertiary and one an all-carbon-atom quaternary stereocenter, in high yield and optical purity. It is noteworthy that the reaction does not require that substrates should be activated by aryl substituents.

Two coordination polymers with the formula of [M2 (DPA)2(C4O4)(C2 O4)]? (M = Cu 1, Zn 2; DPA = dipyridylamine) were synthesized under hydrothermal conditions. Both complexes are crystallized in triclinic system, space group P1 with the cell parameters: a = 8.3078(3) A, b= 9.1192(3) A, c = 9.2316(3) A, alpha = 115.164(1), beta = 94.283(1), gamma = 103.559(1), V = 603.17(4) A3, Z = 2 for complex 1 and a = 8.5348(2) A, b = 9.0451(2) A, c = 9.0862(3) A, alpha = 114.305(1) beta = 100.493(1), gamma = 97.318(1), V = 612.34(2) A3, Z = 2 for complex 2, respectively. X-ray single-crystal structural determinations reveal that these two complexes are both composed of one-dimensional zigzag chains built up via the [M(DPA)]2+ fragments and alternately bridged bidentate mu1,3-C4O42-, tetradentate C2O42- ligands. The coordination environments of the M(II) centers adopt a slightly distorted trigonal bipyramid bonded with two N atoms of DPA, one O atom of squatate and two O atoms of oxalates. The intrachains NH ··· O and C-H ··· O hydrogen bonds play an important role on the additional stabilization in constructing the open frameworks.

The new triply-bridged dinuclear copper(II) complexes, [Cu2(mu-O2CH)(mu-OH)2(dpyam)2](ClO4) · H2O (1), [Cu2(mu-O2CCH3)(mu-OH)(mu-OH2)(dpyam)2](S2O8) (2), [Cu2(mu-O2CCH3)(mu-OH)(mu-OH2)(bpy)2](NO3)2 (3), [Cu2(mu-O2CCH3)(mu-OH)(mu-OH2)(phen)2](BF4)2 · 0.5H2O (4), [Cu2(mu-O2CCH2CH3)(mu-OH)(mu-OH2)(phen)2](NO3)2 (5) and [Cu2(mu-O2CCH3)(mu-OH)(mu-Cl)(bpy)2]Cl · 8.5H2O (6) (dpyam = di-2-pyridylamine, bpy = 2,2?-bipyridine, phen = 1,10-phenanthroline), have been synthesized and characterized crystallographically and also their spectroscopic and magnetic properties have been studied. A structural classification of this type of dimers, based on the data obtained from X-ray diffraction analysis in the present work and those reported in the literature has been performed. In these complexes, the local geometry around the copper centre is generally a distorted square pyramid and distorted trigonal bipyramid with different degrees of distortion. The global geometry of the dinuclear complexes can be described in terms of the relative arrangement of the two five-coordinate environments, giving rise to different classes (A-F) of complexes. The most logical explanations have been provided for each class describing different magnetic interactions. Practically, there is a clear correlation between structural data and J values of the class B complexes. Extended Hu?ckel calculations were performed for the present complexes 1-6, as well as for some other class B complexes, showing the different molecular orbitals involved in their corresponding frontier orbitals, together with their energy. The results are found to be useful for the proper interpretation and correlation of the magnetic data and the dinuclear structure of the present complexes.
