Synthesis of 5-Aroyl-2-aryl-3-hydroxypyridin-4(1H)-ones
Molbank, 2023 A two-stage synthesis of 5-aroyl-2-aryl-3-hydroxypyridin-4(1H)-ones (56–66% overall yields) was carried out by refluxing 5-aroyl-3-(benzyloxy)-2-(het)aryl-4H-pyran-4-ones with ammonium acetate in AcOH and subsequent debenzylation.

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis
Asian Journal of Organic Chemistry, EarlyView.This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

Is Mycobacterial InhA a Suitable Target for Rational Drug Design?
ChemMedChem, EarlyView.InhA is the target of isoniazid, a first‐line antituberculosis drug. Isoniazid is, in fact, a prodrug that needs to be activated. Researchers are trying to develop direct inhibitors of InhA. This includes the resolution of crystallographic structures. The Protein Data Bank contains over a hundred InhA structures.
