Article Abstract
Transformation of sugars, while maintaining the intrinsic stereochemical structure, is desirable. However, such a transformation requires multistep synthesis with protection and deprotection of the OH groups. Herein, a new method for selective transformation of sugar derivatives into chiral building blocks and a diol synthon, with retention of the intrinsic configuration (stereo- and regioselectively), is demonstrated. The method is based on the selective recognition of cis-vicinal OH groups in sugars and leads to the one-pot removal of the cis-vicinal OH groups, without protection of OH groups (except the OH group of the hemiacetal group), over a heterogeneous CeO -supported ReO and Pd (ReO -Pd/CeO ) catalyst by using H as a reducing agent.

The German Federal Ex Situ Genebank for Agricultural and Horticultural Crops (IPK) harbours over 3000 pea plant genetic resources (PGRs), backed up by corresponding information across 16 key agronomic and economical traits. The unbalanced structure and inconsistent format of this historical data has precluded effective leverage of genebank accessions, despite the opportunities contained in its genetic diversity. Therefore, a three-step statistical approach founded in linear mixed models was implemented to enable a rigorous and targeted data curation.

Lignocellulosic biomass is a carbon-neutral resource crucial to advancing a bio-based economy. The filamentous fungus Talaromyces cellulolyticus demonstrates superior biomass saccharification efficiency compared to conventional enzyme-producing fungi, making it a promising host for enzymatic biomass conversion. To enable molecular studies, we developed a robust genetic transformation system for T.

Platinum-group metal half-sandwich complexes are considered to be potential replacements of the clinically widely used platins which have several side effects and tend to cause resistance to develop. In our previous works, we used a range of 2-pyridyl-substituted N- and C-glycosyl heterocycles as N,N-chelating ligands to prepare ruthenium(II), osmium(II), iridium(III) and rhodium(III) polyhapto arene/arenyl half-sandwich complexes. Some of these complexes, particularly with the C-glucopyranosyl isoxazole derived ligand in its O-perbenzoylated form, exhibited greater anticancer efficiency than cisplatin and had minimal or negligible effects on non-transformed fibroblasts.

Ketonyl -glycosides, a vital subclass of alkyl -glycosides, play essential roles in drug discovery, biochemistry, and materials sciences. However, a practical strategy that merges bench-stable glycosyl donors with styrenes-a ubiquitous class of synthetic building blocks-remains elusive. Herein, we report a simple and general approach for synthesizing ketonyl -glycosides.
