Lienhwalides: Unique Tropolone–Maleidride Hybrids from Hypoxylon lienhwacheense

ChemBioChem, EarlyView.
Lienhwalides are novel tropolone–maleidride hybrid molecules unique in nature. Absolute configuration is solved by semisynthetic approaches and X‐ray analysis. Interplay between both lwt and lwm biosynthetic gene clusters is responsible for the production of lienhwalides.

Synthesis of α‐Arylglycosides by Ni‐Photoredox Arylation of Sugars with an Organic Photocatalyst

ChemCatChem, Accepted Article.
Herein we report a Ni‐photoredox catalytic methodology for the synthesis of C‐aryl glycosides via arylation of monosaccharides unprotected at the anomeric position. In our work, the iridium‐complex previously employed as photocatalyst in this kind of Ni‐photoredox arylation of alcohols, was replaced by 5CzBN – a readily available donor‐acceptor ...

Ammoxidation of Unprotected Glycosides: A One‐Pot Conversion of Alcohols to Nitriles

Chemistry – A European Journal, EarlyView.
Efficient C5‐selective ammoxidation of minimally protected carbohydrates enables direct access to nitrile sugars, valuable in bioorthogonal chemistry and drug development. Using TEMPO, PIDA, and ammonium acetate in aqueous acetonitrile, this method offers high selectivity without protecting groups.

Immunological and Toxicological Assessment of Triterpenoid Saponins Bearing Lewis‐X‐ and QS‐21‐Based Trisaccharides

Chemistry – A European Journal, EarlyView.
The synthesis of betulinic acid and echinocystic acid saponins featuring QS‐21 minimal immunogenic motif is reported. These chimeric saponins, together with previously synthesized Lewis‐X‐containing triterpenoid saponins and a rhamnose‐modified saponin, were assessed for their toxicological and immunological profiles in wild‐type and/or hDC‐SIGN ...
