Aminomethylation/hydrogenolysis as an alternative to direct methylation of metalated isoquinolines – a novel total synthesis of the alkaloid 7-hydroxy-6-methoxy-1-methylisoquinoline

Beilstein Journal of Organic Chemistry, 2018
Highly-substituted isoquinolines are important scaffolds in syntheses of natural products and in drug development and hence, effective synthetic approaches are required.

Development of a Self‐Adjuvanting Influenza Peptide–Glycolipid Conjugate Inducing CD8+ T‐Cell Immunity

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The glycolipid‐peptide antigen complexes for self‐adjuvanting conjugates were successfully synthesized, and, with the HLA‐transgenic mice, the antigen‐specific CD8+ T cell expansion was exhibited. The results provide useful insights for the design and synthesis of vaccine conjugates using glycolipid antigen as an adjuvant.

Liquid‐Phase Syngas‐To‐Methanol at Low Temperature: Mixed Alcohol Solvent‐Controlled Pathways for Circular Carbon Manufacturing

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Low‐temperature liquid‐phase methanol synthesis from syngas was demonstrated over CuO/ZnO/Al2O3 catalysts using mixed alcohol solvents. Solvent composition controls ester intermediate and methanol productivity. Methanol is a primary platform chemical for circular manufacturing.
