“…Biomass is considered one of the best alternatives of fossil resources for both energy and chemicals . Usage of biomass through green chemical technology is an effective way to ensure sustainable development of human society . Although this field is well‐recognized and sustainability idea is known, the primary requirement nowadays is to develop good procedures for organic synthesis with bio‐derived blocks and there is a keen interest in exploring chemical reactivity of biomass‐derived platform compounds .…”

The value-added chemicals derived from lignocellulosic resources are mainly oxygen-containing compounds while nitrogen-containing compounds are also important in the industry and ambitiously desired to be obtained from bio-based carbohydrates. Here we report an efficient two-step approach from fructose under mild conditions to obtain N-(5-methylfurfuryl)aniline, a necessary nitrogenous intermediate for some important epoxyisoindoles which have good combat-Alzheimer's and antitumor biological activities. First, 5-methylfurfural was prepared with HI and H 3 PO 3 in a biphasic solution from fructose, then it was isolated and used for N-(5-methylfurfuryl)aniline synthesis through reductive amination catalyzed by a heterogeneous palladium catalyst. Besides, the substrate scope of the amines was examined, and most of them showed very good results. With this approach, renewable N-(5-methylfurfuryl)aniline was produced from fructose in an overall yield of 62%.[a] Dr.

FredrikB jçrnerbäck andN iklas Hedin* [a] Highly porousa nd hyper-cross-linked polymers (HCPs) have a range of applications and are typicallys ynthesized in an unsustainable manner.H erein, HCPs were synthesized from abundant biobased or biorelatedc ompounds in sulfolane with iron(III) chloride as Lewis acid catalyst. As reactants, quercetin, tannic acid, phenol, 1,4-dimethoxybenzene, glucose, and a commercial bark extract wereu sed. The HCPs had high CO 2 uptake (up to 3.94 mmol g À1 at 0 8Ca nd 1bar), total pore volumes (up to 1.86 cm 3 g À1 ), and specific surfacea reas (up to 1440 m 2 g À1 ). 1 HNMR, 13 CNMR, and IR spectroscopy,w ideangle X-ray scattering, elementala nalysis, and SEM revealed, for example, that the HCPs consisted of amorphous and crosslinked aromatic and phenolic structures with significant contents of aliphatics, oxygen, and sulfur.[a] Dr.

Green, General and Low‐cost Synthesis of Porous Organic Polymers in Sub‐kilogram Scale for Catalysis and CO₂ Capture

Porous organic polymers (POPs) with high porosity and tunable functionalities have been widely studied for use in gas separation, catalysis, energy conversion and energy storage. However, the high cost of organic monomers, and the use of toxic solvents and high temperatures during synthesis pose obstacles for large-scale production. Herein, we report the synthesis of imine and aminal-linked POPs using inexpensive diamine and dialdehyde monomers in green solvents. Theoretical calculations and control experiments show that using meta-diamines is crucial for forming aminal linkages and branching porous networks from [2+2] polycondensation reactions. The method demonstrates good generality in that 6 POPs were successfully synthesized from different monomers. Additionally, we scaled up the synthesis in ethanol at room temperature, resulting in the production of POPs in sub-kilogram quantities at a relatively low cost. Proof-of-concept studies demonstrate that the POPs can be used as highperformance sorbents for CO 2 separation and as porous substrates for efficient heterogeneous catalysis. This method provides an environmentally friendly and costeffective approach for large-scale synthesis of various POPs.
