Synthesis of bicyclic tertiary alpha-amino acids

Novel bicyclic alpha-amino acids, exo and endo-1-azabicyclo-[2.2.1] heptane-2-carboxylic acid, 1-azabicyclo[2.2.1]heptane-7-carboxylic acid, and 1-azabicyclo[3.2.2]nonane-2-carboxylic acid have been readily synthesized for the generation of neuronal nicotinic receptor ligands. Alkylation of glycine-derived Schiff bases or nitroacetates with cyclic ether electrophiles, followed by acid-induced ring opening and cyclization in NH4OH, allowed for the preparation of substantial quantities of the three tertiary bicyclic alpha-amino acids.

Supported metal catalysts for total hydrogenation of furfural and 5-hydroxymethylfurfural

Total hydrogenation of furfural and 5-hydroxymethylfurfural (HMF), both of which are important platform chemicals from biomass, produces tetrahydrofurfuryl alcohol (THFA) and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHTHF), respectively, and these products can be used as solvent or raw material of resin. Ni catalysts can give good yields in these reactions; however the low activity and stability are problems. Supported monometallic Pd and Ru catalysts have been reported to be also active in hydrogenation, although the selectivity for total hydrogenation tends to be lower. Other monometallic catalysts such as Cu and Pt generally have low activity in furan ring hydrogenation of furfuryl alcohol (FOL) and 2,5-bis(hydroxymethyl)furan intermediates. We explored various multicomponent catalysts and found that Ni-Pd/SiO2, Pd-Ir/SiO2 and Rh-Ir-ReOx/SiO2 give good yield of THFA or BHTHF with much higher activity than the mixture of each component supported on SiO2.

Total synthesis of gonytolides C and G, lachnone C, and formal synthesis of blennolide C and diversonol

The first stereoselective total synthesis of gonytolide C, which is a monomeric unit of an innate immune promoter gonytolide A, has been accomplished from the aldol reaction between acetophenone derived from orcinol and butyrolactone containing alpha-keto ester followed by the excellent diastereoselective intramolecular cyclization. The first total synthesis of gonytolide G has been achieved by the oxidation of benzylic methyl in gonytolide C. Additionally, total synthesis of lachnone C and a formal synthesis of blennolide C and diversonol have been achieved by this synthetic method. the Partner Organisations 2014.

Solvent-free Hydrodeoxygenation of Gamma-Nonalactone on Noble Metal Catalysts Supported on Zirconia

The possibility to valorize levulinic acid (LA) dimers to lignocellulose-based biofuels via hydrodeoxygenation (HDO) was assessed using gamma-nonalactone (GNL) as a model compound. Catalytic HDO experiments were performed in a batch reactor at 280 C and at an average pressure of 57.5 bar H2. Noble metal (Ru, Rh, Pd, and Pt) catalysts supported on ZrO2. All the catalysts were active in removing oxygen from the reactant. However, the most selective catalyst for hydrocarbons (24%) was ruthenium. Unlike the other tested catalysts, Ru also provided branched hydrocarbons. In view of Ru?s comparatively high selectivity to hydrocarbons, it was tested at various reaction temperatures (220?280 C) for 300 min. The experiments at lower temperatures resulted in less hydrocarbons and more intermediate products, such as alcohols. In total, nearly 70 products were identified, and some of the reactions that likely occurred in the HDO experiments were discussed. The production of hydrocarbons from GNL highlights the potential of LA dimers as a route to lignocellulose-based biofuels.
