Palladium-catalyzed synthesis of bis-glycosides of but-2-ene-1,4-diol, butane-1,4-diol, and 1,2-bis(propenyl)benzene

Palladium(0)-catalyzed reaction of various carbohydrates derived from glucofuranose, mannofuranose, ribofuranose, glucopyranose, and glucosamine, beating a free hydroxyl group, with 1,4-bis-(methoxycarbonyloxy)but-2-ene afforded the corresponding bis-glycosides of butene-1,4-diol. Hydrogenation in the presence of palladium on charcoal of these unsaturated compounds led to the formation of the bis-glycosides of butane-1,4-diol. The condensation was successfully extended to the bis-carbonate of 1,2-bis-[(1-hydroxy)propen-2-yl]benzene and derivatives of glucofuranose, ribofuranose and glucosamine.

One-pot enzymatic desymmetrization and Ugi MCR

A new approach to the synthesis of chiral peptidomimetics is reported. It combines an enzymatic desymmetrization of 3-phenylglutaric anhydrides with a subsequent Ugi multi-component reaction in a one-pot, two-step procedure. NMR and CD spectroscopy was used to assign the configurations of obtained products. Our synthetic method is very efficient and it can easily be extended to other types of multi-component reactions and can be used for the preparation of chiral peptidomimetic libraries.

Catalytic Depolymerization of Chitin with Retention of N-Acetyl Group

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.
