The chitin obtained from crustacean shell waste and other renewable resources may be used as a primary feedstock in the biorefineries of the future. Accordingly, the incorporation of chitin-derived building blocks into new synthesis processes will accentuate the utility of this biopolymer, particularly in the production of bio-based small molecules that contain one or more nitrogen atoms. Herein we report that enantioenriched 2-amino sugars are readily accessible from the chitin-derived platform 3-acetamido-5-acetylfuran (3A5AF). Subjecting 3A5AF to a Noyori reduction?Achmatowicz rearrangement sequence gave N-acetyl-l-rednose (RedNAc) in excellent yield and enantiopurity. Acetamide hydrolysis gave l-rednose, a rare 2-amino sugar found in natural anthracycline and angucycline antibiotics. RedNAc was subsequently shown to be a versatile platform from which a variety of stereochemically pure 2-amino sugars are readily attainable. The synthesis of chiral, bio-based N-compounds from chitin emphasises the rapidly expanding utility of this biopolymer as a viable platform for fine chemical production.

The reactivities and the site-selectivities of the hydrolyses of ATP and UTP by the catalysts of the metal complexes of adenine-linked di-2-pyridylamine ligands, (Py)2N-(CH2)n-Ade (L: n = 3, 4, 5, and 6), were examined. It was found that these adenine-dipyridylamine coordinated Cu2+ complexes (with 2:1 ratios of [CuII(L)]2+ : ATP or [CuII(L)]2+ : UTP) were more reactive for the hydrolyses of ATP and UTP than the complexes of ligands containing other metal ions (Mg2+, Ni2+, and Zn2+) at 40C and pH 7.3 (HEPES buffer), as reflected in much higher product ratios of ADP/AMP and UDP/UMP than those of Cu2+ alone. The observed high reactivity and selectivity are interpreted in terms of the base-base stackings between an adenine moiety of ATP or an uracil moiety of UTP and an adenine of the ligands, and of the selective coordination of Cu2+ to oxide ions in phosphate residues in the ternary complexes of ligand-Cu2+-ATP. The Cu2+-complex of di-2-pyridylamine having no adenine moiety, which is the active center of [CuII(L)]2+, promoted the hydrolyses of ATP and UTP less efficiently than the aquacopper(II) ion. The number of spacer methylene groups of the ligands influenced the hydrolytic activity of the Cu2+-complexes of these adenine-dipyridylamine ligands. The complexes of [CuII(L-4)]2+ and [CuII(L-5)]2+ were the most reactive and site-selective for the hydrolyses of ATP and UTP, respectively.

Two novel carbohydrate-derived pyridyl (PYOX)- and cyclopropyl (CYBOX)-substituted oxazoline ligands were prepared from D-glucosamine hydrochloride and 1,3,4,6-tetra-O-acetyl-2-amino-2-deoxy-beta-D-glucopyranose hydrochloride in two steps, respectively. The sugar-annulated PYOX ligand formed a stable metal complex with Pd(II), which was fully characterized by NMR spectroscopy and X-ray crystallography. NMR and X-ray analysis revealed a change of the conformation in the sugar moiety upon complexation with the palladium(II) species. Both glycosylated ligands resulted in high asymmetric induction (up to 98% ee) upon application as chiral ligands in the Pd-catalyzed allylic alkylation of rac-1,3-diphenylallyl acetate with dimethyl malonate (Tsuji-Trost reaction). Both ligands provided mainly the (R)-enantiomer of the alkylation product.

Three new triply-bridged dinuclear copper(II) compounds with carboxylato bridges, [Cu2(mu-O2CH)(mu-OH)(mu-Cl)(dpyam) 2](PF6) (1), [Cu2(mu-O2CH) 2(mu-OH)(dpyam)2](PF6) (2) and [Cu 2(mu-O2CCH2CH3) 2(mu-OH)(dpyam)2](ClO4) (3) (dpyam = di-2-pyridylamine) have been synthesized and characterized crystallographically and spectroscopically. Compound 1 consists of a dinuclear unit in which both copper(II) ions are bridged by three different ligands, i.e., formate, chloride and hydroxide anions, providing a distorted trigonal bipyramidal geometry with a CuN2O2Cl chromophore. Compounds 2 and 3 have two bridging formato ligands and two bridging propionato ligands, respectively, together with a hydroxo bridge. The carboxylato ligands in both compounds 2 and 3 exhibit different coordination modes. One is in a syn, syn eta1: eta1:mu2 bridging mode and the other is in a monoatomic bridging mode. The structure of compound 2 involves a dinuclear unit, with a distorted trigonal bipyramidal geometry around each Cu(II) ion with a CuN2O3 chromophore. Compound 3 contains a non-centrosymmetric unit; the coordination environment around Cu(1) is a distorted square-pyramidal geometry and an intermediate geometry of sp and tbp around the Cu(II) ion. The Cu?Cu separations are 3.061, 3.113 and 3.006 A? for compounds 1, 2 and 3, respectively. The EPR spectra of all three compounds show a broad isotropic signal with a g value around 2.10. The magnetic susceptibility measurements, measured from 5 to 280 K, revealed a moderate ferromagnetic interaction between the Cu(II) ions with a singlet-triplet energy gap (J) of 79.7, 47.8 and 24.1 cm-1, for compounds 1, 2 and 3, respectively. Also a very weak intermolecular antiferromagnetic interaction was observed between the dinuclear units.

As expected, the reactive acetyl-protected O-(alpha-D-glucopyranosyl) trichloroacetimidate 3 reacts with S-nucleophiles and trifluoroborane-ether as catalyst to yield exclusively 1-thio-beta-D-glucopyranosides with inversion of the configuration.The corresponding benzyl-protected alpha-trichloroacetimidate 4 affords with retention of the configuration alkyl 1-thio-alpha-D-glucopyranosides.The importance of alkyl 1-thio-beta-D-galactopyranosides in enzyme induction was reason to apply this convenient and efficient glycosyl-transfer reaction to the synthesis of isopropyl 1-thio-beta-D-galactopyranoside (12a) and the sodium salt of 1-thio-beta-D-galactopyranose (12b), respectively.
