Practical aqueous reactions leading to skeletally diverse carbohydrate-derived ketones

Four types of skeletally diverse compounds have been synthesized from protected aldosyl hemiacetals and methyl ketones using cheap catalysts in water in one pot. Among the four skeletons, two of them are not accessible by current methods. The reactions are operationally simple, high yielding and scalable, which opens a practical channel for utilizing carbohydrates to produce chemical and pharmaceutical intermediates and products.

Rational design of bifunctional hierarchical Pd/SAPO-5 for the synthesis of tetrahydrofuran derivatives from furfural

The one-pot aldol condensation/crotonization reaction between furfural and methyl isobutyl ketone (MIBK), followed by hydrogenation with molecular H2, was implemented for preparing tetrahydrofuran derivatives. To this aim, we developed a robust Pd/HPSAPO-5 catalyst based on the crystalline silico-aluminophosphate SAPO-5 with hierarchical porosity and optimized silicon content. The hierarchical HPSAPO-5 catalyst was synthesized using a bottom-up method starting from pre-synthesized MCM-41, with the surfactant (CTAB) inside the mesopores, serving both as Si source and mesoporogen. NH3-TPD and FT-IR spectroscopy of adsorbed probe molecules combined with solid-state 1H MAS NMR were used to assess the nature, strength and accessibility of the acid sites. The structural and textural properties of the catalysts were investigated using X-ray diffraction (XRD) and N2 adsorption. HR-TEM was used to assess the dispersion and location of Pd nanoparticles on HPSAPO-5. The spent catalyst could be restored and reused after calcination.

Direct Catalytic Conversion of Furfural to Furan-derived Amines in the Presence of Ru-based Catalyst

The production of amine intermediates from biomass is capturing increasing attention. Herein, a simple and efficient preparation of l furan-derived amines was developed [e.g., 1-(furan-2-yl)-4-methylpentan-2-amine] with high yield (up to 95 %) from (E)-1-(furan-2-yl)-5-methylhex-1-en-3-one. The catalyst used was Ru/C, and it was recyclable up to the fourth cycle. To further realize cost-efficiency, a one-reactor tandem concept was attempted. To this aim direct reaction from furfural was investigated. A high yield (74 %) towards 1-(furan-2-yl)-4-methylpentan-2-amine could be achieved starting directly from furfural in the presence of methyl isobutyl ketone, NH3, H2, and Ru/C catalyst.
