Chitin, a polymer of N-acetylglucosamine units with beta-1,4-glycosidic linkages, is the most abundant marine biomass. Chitin monomers containing N-acetyl groups are useful precursors to various fine chemicals and medicines. However, the selective conversion of robust chitin to N-acetylated monomers currently requires a large excess of acid or a long reaction time, which limits its application. We demonstrate a fast catalytic transformation of chitin to monomers with retention of N-acetyl groups by combining mechanochemistry and homogeneous catalysis. Mechanical-force-assisted depolymerization of chitin with a catalytic amount of H2SO4 gave soluble short-chain oligomers. Subsequent hydrolysis of the ball-milled sample provided N-acetylglucosamine in 53 % yield, and methanolysis afforded 1-O-methyl-N-acetylglucosamine in yields of up to 70 %. Our process can greatly reduce the use of acid compared to the conventional process.

(Chemical Equation Presented) A novel approach to the synthesis of Fmoc-protected neoglycopeptide building blocks is described. Oxidation of N-acetyl-D-glucosamine isonitrile afforded the corresponding highly reactive glycopyranosyl isocyanate, which reacted with amino acid derivatives to furnish the corresponding urea- and carbamate-tethered Fmoc-protected N-acetyl-D-glucosamine amino acid conjugates in good yields.

The reaction of 2,2?-dipyridylamine with R3M (R = CH3, M = Ga, Al) gave the Lewis acid-base adducts Me2Ga(dpa) and Me2Al(dpa) (where dpa is 2,2?dipyridylamide). X-ray analysis showed an unusual structure of dpa- in the formation of a new anti-anti complex Me2Ga(dpa) with extremely short bond distances Ga-N(1) [1.976(3) A] and Ga-N(2) [1.978(3) A]. The gallium atom is in a tetrahedral environment, coordinated to the deprotonated chelating ligand and two methyl groups. The bond distances N(3)-C(5) [1.345(4) A] and N(3)-C(6) [1.347(4) A] are almost identical. The bond angle N(1)-Ga-N(2) [92.0(1)] is 17 smaller than, and C(12)-Ga-N(1) [109.5(2)] is almost equal to, normal tetrahedral angles. These adducts are much less air- and moisture-sensitive than the metal trialkyl. The compounds were characterized by elemental analysis, NMR and mass spectroscopy. The conformation of the dipyridylamide ligand in the bidentate chelate complex is significantly different from that observed for other dipyridylamine complexes. Copyright

This paper reports the selective oxidation of hyaluronic acid (HA) by stoichiometric quantity of 2,2,6,6-tetramethylpiperidine-1-oxoammonium chloride (TEMPO+) in aqueous alkaline medium. High efficiency of the HA oxidation and quantitative yield of carboxy-HA per starting TEMPO+, as well as unusual behavior of the oxidation system generating an oxygen upon alkali-induced oxoammonium chloride decomposition are demonstrated. The scheme for HA oxidation involving both TEMPO+ and oxygen produced upon the TEMPO+Cl- decomposition and/or air oxygen is proposed. For comparison, the data on stoichiometric oxidation of such substrates as dermatan sulfate, water-soluble potato starch, methyl 2-acetamido-2-deoxy-beta-d-glucopyranoside and ethanol are presented.
