Abstract
The shift towards sustainable feedstocks for platform chemicals requires new routes to access functional molecules that contain heteroatoms, but there are limited bio-derived feedstocks that lead to heteroatoms in platform chemicals. Combining renewable molecules of different origins could be a solution to optimize the use of atoms from renewable sources. However, the lack of retrosynthetic tools makes it challenging to examine the extensive reaction networks of various platform molecules focusing on multiple bio-based feedstocks. In this study, a protocol was developed to identify potential transformation pathways that allow for the use of feedstocks from different origins. By analyzing existing knowledge on chemical reactions in large databases, several promising synthetic routes were shortlisted, with the reaction of D-glucosamine and pyruvic acid being the most interesting to make pyrrole-2-carboxylic acid (PCA). The optimized synthetic conditions resulted in 50 % yield of PCA, with insights gained from temperature variant NMR studies. The use of substrates obtained from two different bio-feedstock bases, namely cellulose and chitin, allowed for the establishment of a PCA-based chemical space.

Abstract
![]()
An effective visible-light-promoted
iridium(III)-catalyzed hydrogen
production from N-heterocycles is described. A single iridium complex
constitutes the photocatalytic system playing a dual task, harvesting
visible-light and facilitating C–H cleavage and H2 formation at room temperature and without additives. The presence
of a chelating C–N ligand combining a mesoionic carbene ligand
along with an amido functionality in the IrIII complex
is essential to attain the photocatalytic transformation. Furthermore,
the IrIII complex is also an efficient catalyst for the
thermal reverse process under mild conditions, positioning itself
as a proficient candidate for liquid organic hydrogen carrier technologies
(LOHCs). Mechanistic studies support a light-induced formation of
H2 from the Ir–H intermediate as the operating mode
of the iridium complex.

Abstract
Exploring low-energy reaction pathway of catalytic biomass conversion can lead to wider application and the achievement of sustainability objectives. Since glucose dehydrogenation to gluconic acid and H 2 is a cost-effective alternative to glucose oxidation, this study aims to elucidate its mechanism. The detection of lactone as an intermediate indicates that cyclic glucose reacts directly via its hemiacetal group-ring opening is not involved; that is, cyclic glucose is dehydrogenated to lactone, which is further hydrolyzed to gluconic acid. The source of hydrogen is confirmed to be glucose and water by Isotope tracing confirms. Density function theory (DFT) calculations demonstrate that Hemiacetal Dehydrogenation Pathway (this work) is less energy intensive than Ring-opening Oxidation Pathway (previous works). This study provides a new dehydrogenation strategy to produce gluconic acid and H 2 from biomass under mild conditions.

Abstract
Two sets of carbohydrate‐NHC hybrid iridium complexes were synthesised in order to combine properties of carbohydrates and triazolylidene (trz) ligands in organometallic catalysis. One set features a direct trz linkage to the anomeric carbohydrate carbon, while the second set is comprised of an ethyl linker between the two functional units. Deprotection of the carbohydrate afforded hybrid complexes that efficiently catalyse the direct hydrogenation of ketones in water. The catalytic activity of the hybrid complexes was influenced by the pH of the aqueous medium and surpassed the activity of carbohydrate‐free or acetyl‐protected analogues (>90 % vs 13 % yield). While no enantiomeric induction was observed for the ethyl‐linked hybrids, a moderate enantiomeric excess (ee) was induced by the directly linked systems. Moreover, these carbohydrate‐trz hybrid complexes displayed mixed inhibitory activity towards a glycosidase from H. orenii that contain a glucose binding site.
