Abstract Dehydration of biomass‐derived levulinic acid under solid catalysis and treatment the resulting angelica lactone with catalytic K 2 CO 3 produces dimer in excellent yield. This serves as a novel feedstock for hydrodeoxygenation, which proceeds relatively mild conditions combination oxophilic metal noble catalysts to yield branched C 7 –C 10 hydrocarbons gasoline volatility range. Considering that is available >80 % conversion from raw biomass, field‐to‐tank drop‐in, cellulosic...
A simple, non-fermentative, high-yielding, metal-free, chemical-catalytic pathway to succinic acid from biomass-derived levulinic is reported.
A handful of small organics, namely, ethylene, propylene, butadiene, benzene, toluene, xylenes, and methanol, produced from petroleum other fossilized carbon-based resources, can produce practically all petrochemicals synthetic organic polymers used in the industrialized societies. The molecules mentioned above, often referred to as primary petrochemicals, must be sourced renewable carbon feedstock achieve long-aspired all-around sustainability chemical manufacturing. Significant efforts...
Cellulose-derived 5-(chloromethyl)furfural is converted into δ-aminolevulinic acid in three chemical steps involving conversion to 5-(azidomethyl)furfural, photooxidation, and catalytic hydrogenation 68% overall yield. δ-Aminolevulinic a natural product with important agrochemical pharmaceutical applications.
The biomass-derived platform chemical 5-(chloromethyl)furfural is converted into the blockbuster antiulcer drug ranitidine (Zantac) in four steps with an overall 68% isolated yield.

2,5-Dimethylfuran (DMF) is one of the most actively pursued biomass-derived chemicals due to fact that it can serve both as a biofuel and an intermediate for drop-in terephthalate polymers. DMF be accessed via catalytic hydrogenation 5-(hydroxymethyl)furfural (HMF), but difficult accessibility HMF from cellulosic biomass major impediment commercial development such process. Alternatively, 5-(chloromethyl)furfural (CMF) freely accessible in high yield directly raw shown here efficiently...
Prothrin, a synthetic pyrethroid insecticide, was synthesized from the biomass-derived platform chemical 5-(chloromethyl)furfural in six steps and overall 65% yield. Two structural analogues of prothrin were also prepared following same approach. Preliminary testing these furan-based pyrethroids against yellow fever mosquito Aedes aegypti indicates promising insecticidal activities.
A discrete dinuclear Ag(I) complex undergoes a single-crystal-to-single-crystal transformation to generate 1D coordination polymer with polycyclobutane backbone.
Polyoxometalates (POMs) are promising inorganic inhibitors for P-type ATPases. The experimental models used to study the effects of POMs on these ATPases usually in vitro using vesicles from several membrane sources. Very recently, some polyoxotungstates, such as Dawson anion [P2W18O62]6−, were shown be potent ATPase inhibitors; being active well ex-vivo. In present we broaden spectrum highly Na+/K+-ATPase basal epithelial skin bi-capped Keggin-type phosphotetradecavanadate Cs5.6H3.4PV14O42...

Abstract 3‐Hydroxypropanoic acid (HPA), a precursor to acrylic acid, can be produced in high yield by oxidation of the biomass‐derived platform chemical levulinic acid. While treatment with H 2 O under acidic conditions gives predominantly succinic remarkable reversal selectivity is observed basic conditions, leading either directly HPA or, modified initially 3‐(hydroperoxy)propanoic which quantitatively hydrogenated HPA.
